Historic Environment Scotland (HES) has announced that conservation works have begun at Kisimul Castle.

The works will look to address concerns related to the concrete and its reinforcement bars, which shifted during the pouring process when the castle underwent a major restoration in the 20th century. The coastal location of the site has caused moisture and salt to corrode the steel reinforcement bars, which were set too close to the concrete faces. Concrete slabs have also become cracked and weakened over time, with concrete covers in other areas having been deemed an insufficient thickness to provide long-term protection.

Helicopter deliveries have transported heavy equipment and materials to the site given its location, allowing specialist conservation teams to begin the introduction of new support systems for the concrete.

Head of North Region at HES, Jamie McPherson, said:

“We know the significance of Kisimul Castle to the community who are keen to see increased access to the site. It has faced some complex conservation challenges, some of which are historic and have been compounded by factors including climate change. We’re pleased to be able to begin these works which will allow us to facilitate further work and will help to achieve the longer-term goal of reopening the castle to the local community and visitors.”

Initial phases of these reinforcement works will also allow safe access for high-level masonry inspection teams who will undertake tactile surveys to review the condition of masonry at the castle. This programme of inspections was established to assess the effects of climate change on some of HES’s properties in care, in combination with other factors. Results from the inspection will help to inform the ongoing programme of works at the castle.
