Again in the summertime of 2020 once we started reopening our castles, abbeys and palaces, we knew this was an vital milestone. It was a logo of hope that there have been higher instances forward past the pandemic. These outdated buildings had been testimony to a way of the everlasting that connects us by means of the generations, to what makes us human, and to what retains us shifting ahead within the face of adversity. However the care of those vital locations additionally poses a rising problem.
Getting ready to reopen Edinburgh Citadel in summer season 2020.
As we had been starting to open up once more, sadly there have been some extra issues looming on the horizon. Earlier than the pandemic we’d began work on a mission which has come to have a big impression on Scotland’s historic locations.
Website groups had turn into conscious of a rise in small items of masonry changing into dislodged at a handful of web sites. Though we had a programme of rolling inspections and repairs in place, it was changing into apparent that we would have liked to take a brand new strategy to completely perceive and deal with this.
Years within the planning
In 2019 we recruited a mission workforce to tackle the problem of assessing the situation of web sites round Scotland. We prioritised areas the place we had issues that there may doubtlessly be a danger of harm to guests and workers. This included all properties with masonry over a peak of 1.4 metres.
This workforce was charged with revisiting the steerage and protocols we had in place. The place mandatory, they’d make new suggestions round inspecting our websites. This additionally included reviewing present directions on methods to strategy inspections for gravestones, bushes, flagpoles, plaques and different options.
The workforce spent the latter half of 2019 steeped in preparation planning, with the intention of starting inspections within the spring of 2020. Then the pandemic struck.
Within the spring of 2021, we had been capable of resume inspections safely. These preliminary inspections found there have been areas inside some websites the place the stone and mortar had deteriorated and was doubtlessly problematic. We couldn’t permit guests and colleagues to maintain accessing these monuments realizing that there was a possible danger to life from falling masonry. Legally, we needed to mitigate identified and certain dangers. The quickest approach to try this was to limit entry.
Trigger and impact
We all know that local weather change is inflicting extra rain and extra storms in Scotland. That is having an impression on buildings of all ages. It’s dashing up the decay of our properties, locations of labor, group buildings and culturally and traditionally vital buildings. This can be a development that may proceed until local weather change is tackled on a worldwide degree. The adjustments in our local weather because the Sixties are having a considerable impression on how we glance after the websites in our care.

Additionally, because of the ravages of historical past – together with the Scottish Reformation, sieges, and historic fires – round 30% of the properties we take care of are ruinous. Meaning they’re not as properly protected in opposition to the weather as extra intact buildings. Though measures have been taken to attempt to preserve rain from soaking down into the partitions of unroofed buildings, these efforts aren’t as efficient as a roof at shedding water away from partitions.
Local weather change is one issue taking its toll on Scotland’s historic buildings. It isn’t the one motive, however together with different components it has accelerated the decline. Properly-meaning, however unsympathetic repairs by earlier generations – resembling outdated cement repairs – at the moment are additionally inflicting vital issues.
Raining, plowetery, drookit, smirr
Scotland is known the world over for its rain. Centuries in the past, when these buildings had been first constructed and in use, roofs, gutters and waterspouts diverted rainwater away. This prevented the stonework from changing into saturated. Many would have been harled – lined in a protecting layer of lime render – to maintain the rain from penetrating the stonework. Many are in places like clifftops and hilltops. These had been nice strategic places prior to now for defence and entry by sea, but it surely does imply they’re particularly susceptible to the ravages of the Scottish climate.
When water penetrates uncovered tops of partitions it will possibly trigger injury in a lot of methods. For instance, it will possibly wash away binding supplies, like mortar. Saturated partitions are extra susceptible to break brought on by freezing and thawing. In our now hotter local weather, crops have an extended rising season and readily take maintain within the stonework. It may be troublesome to clear this elevated vegetation progress given the peak and ruinous nature of those buildings.

However did it’s important to shut them unexpectedly?
Over the previous six months, we’ve usually been requested why we couldn’t go away the websites open till we’re prepared to examine them. This merely isn’t an choice. There’s a clear authorized responsibility for us (and anybody else who manages property which is accessed by workers or the general public) to behave rapidly when a possible danger has been recognized. Realizing what we knew in regards to the websites we had inspected, our information prompt a lot of our different websites may very well be harbouring the identical points. Danger components included websites:
- positioned in equally uncovered places
- which had been constructed utilizing like supplies and related constructing methods
- in a ruinous state
We turned notably involved about our websites within the south and central a part of Scotland the place there are many websites that share these traits. For instance, some varieties of stone are very susceptible to weathering and local weather change is accelerating this.
Between November 2021 and January 2022 we took the troublesome resolution to place entry restrictions in place at extra of the websites we take care of. It was with a heavy coronary heart that we put in place entry restrictions at 70 of our websites.
Doune Citadel was one of many 70 websites the place we needed to put in place entry restrictions. It reopened in June. Guests are as soon as once more capable of discover many of the fort, which has featured in Monty Python and the Holy Grail, Recreation of Thrones and Outlander.
Getting a glimpse
Though it was dispiriting to have to limit entry at these websites, we’ve got been capable of keep entry at 80% of the locations we take care of. This consists of offering as a lot entry as potential at websites the place there are restrictions in place. For instance, after inspections at Dryburgh Abbey guests can now entry the grounds and graveyard, nave, and the resting locations of Earl Haig and Sir Walter Scott. The bogs and store are additionally open.
We’ve additionally been working onerous to offer various experiences at websites the place there are restrictions in place. This consists of movies which will be accessed by means of QR codes, and exhibitions and informative graphics at 15 of our websites. We’ll even be trialling a digital actuality expertise of the siege mines at St Andrews Citadel. Look out for our upcoming weblog having a look on the new interpretation experiences we’ve been setting up.
Getting permission
Scheduled Historic Monuments and buildings of nationwide significance have their cultural significance protected by legislation. And similar to anybody else who’s answerable for a legally protected property, we’ve got to hunt permission earlier than we will perform work of any sort on the websites we take care of. Typically, we’ve got to safe Scheduled Monument Consent.
Earlier than our conservation workforce can begin finishing up work on these websites, their plans have to be reviewed and endorsed by specialists working independently inside our Heritage Directorate. It’s their job to contemplate the impacts of any adjustments to a scheduled monument.
In different circumstances, we’ve additionally needed to search recommendation and permission from different our bodies with a statutory function. For instance, NatureScot has a job in defending the pure heritage on and across the locations we take care of. This consists of assessing potential impression on the animals, bugs and plants that share our websites.
Ranging from a robust base
There are a number of components that we have to consider earlier than beginning an inspection. These all add to the planning and timescales.
For instance, many of the locations we take care of are surrounded by buried archaeological stays that aren’t seen above floor. These should not be broken by heavy gear, resembling entry platforms.

Nevertheless, guests can benefit from the customer centre, grounds and a brand new exhibition. They’ll additionally go to the Scriptorium – a office for writers and artists.
Some websites, like church buildings or cathedrals, might have unknown burial lairs. These may probably collapse beneath the burden of the heavy gear we have to use. Geophysical surveys might help determine what’s lurking beneath the bottom. These have been carried out upfront of surveys to provide an image of any archaeological stays not seen on the bottom.
In different circumstances, it has been troublesome to deliver giant items of kit on to a web site.
At Inchcolm Abbey, the specialist entry platform was delivered to the island by boat.
The place we will’t herald gear, inspections are being carried out by rope entry. For instance, at St Andrews Citadel, we’ve not been capable of deliver giant items of kit on to the positioning as a result of the bridge to the positioning has weight and measurement restrictions. This implies the whole lot of the positioning must be inspected by a specialist rope entry workforce.
St Andrews Citadel, the place inspections should be carried out by a rope entry workforce. We might be opening extra of the fort very quickly following its latest inspection. Within the meantime, guests can entry the customer centre, exhibition and bogs.
Searching for our neighbours
Bats, birds, and badgers are all followers of making their properties in Scotland’s historic locations. We’d like to verify we don’t disturb protected wildlife whereas we’re finishing up our surveys. We work with organisations like NatureScot to verify our work gained’t have a adverse impression on our furry, feathered or creepy-crawly associates.
After we began our inspections at Ravenscraig Citadel we discovered some nesting fulmars. This implies we will’t proceed our inspections of the fort till September.
Attending to grips with excessive degree inspections
Throughout the heritage sector, inspections are primarily carried out visually. This might contain specialists inspecting from the bottom with binoculars. For a more in-depth look, inspectors may use an elevated platform or, extra lately, use a drone.
Our technique of thorough tactile inspections of entire buildings is a very new strategy. Our specialists are fairly actually attending to grips with assessing the situation of the stonework at our affected websites. They rise up to the excessive areas of the monuments and bodily push the stones and mortar to see if something is unfastened. This technique supplies essentially the most correct data. We count on it will turn into the gold customary for our sector the world over.
Up to now, our mission workforce has delivered coaching to colleagues so extra of our workers have the abilities to hold out these extremely technical surveys. This even concerned creating a brand new Scottish {Qualifications} Authority qualification, which might be out there to learners throughout the heritage sector.

How lengthy will it take?
The inspections might be carried out as swiftly as potential. This winter, we’re planning to proceed finishing up inspections when climate permits. It may be troublesome to do the inspections throughout the winter resulting from excessive wind speeds and low temperatures. For instance, if gusts of wind exceed 28mph, it’s not secure for our groups to work at peak. Any small repairs utilizing lime mortar have to be accomplished when there isn’t a danger of frost. Frost could cause lime mortar repairs to fail or crack and never ‘remedy’ or set correctly. Nevertheless, our groups might be out daily they will.
Some properties have complicated stonework – carved stones, intricate ornament, or slender window tracery – and can want a programme of extra concerned repairs to be deliberate. Some properties are additionally very giant so there’s a number of stonework to test.
For instance, we estimate that it’s going to take 45 days for our workforce to totally test the stonework at Tantallon Citadel, 22 days at Rothesay Citadel and 30 days at Bothwell Citadel.
At a big web site like Tantallon Citadel it’ll take round 45 days for our groups to examine all of the stonework. Though the fort is out of bounds till we will examine it, guests can nonetheless go to the grounds and store.
All in all, it’s prone to take a few years to hold out the complete inspections on the 206 websites with masonry over 1.4 metres and make suggestions for long run remedial work.
What subsequent?
Because of all of the onerous work and planning of our colleagues, our inspections are on schedule. We’ve already checked our first batch of web sites and have been capable of restore at the least partial entry at a few of these.
The quantity of entry we’re capable of present does fluctuate from web site to web site, relying on what we discover throughout our inspections. For instance, there are only a few restrictions in place at Craigmillar Citadel, however at St Andrews Cathedral we’ve needed to be very cautious about which areas of the positioning we will let workers and guests again into till additional conservation works will be carried out.
At Craigmillar Citadel there are solely very minor restrictions in place following its inspection by the workforce in summer season 2021.
The outcomes of our hands-on inspections have been encouraging. Up to now, we’ve got not found any points which have been a whole shock. Most of the time we’ve been capable of perform a number of smaller repairs as we go. For instance, repairs to slates and lightening conductors, the elimination of invasive weeds, and securing high-level stones in a mattress of mortar.
As soon as we’ve carried out inspections and minor repairs in any respect websites we’ll have a greater concept of the extent of the problem dealing with us. It will allow us to make knowledgeable selections about which main works to prioritise. We’ll additionally know extra in regards to the assets required to hold out extra concerned conservation works.
A world conservation problem
Scotland isn’t alone in dealing with these threats to nationally vital historic buildings. We’re one of many first nations to deal with the problem head on. We’ve obtained a number of curiosity on this mission from heritage organisations everywhere in the world and we’ll be sharing our strategy and studying with colleagues worldwide.
