Stone Conservation

The removal of the bitumen roof was concluded in late summer 2009. Conservators then began work to carefully remove visually disfiguring bitumen runoff, (from the initial application)  found  splashed on the ashlar masonry walls at clerestory level.

The Conservation & Access Project at Rosslyn Chapel has provided the opportunity for advanced practical training in conservation. Two new interns from ICON (Institute of Conservation) and Historic Scotland have joined Nicolas Boyes Stone Conservation and begun work this autumn. The ICON intern can be seen here, removing damaging OPC (Ordinary Portland Cement) from construction joints at clerestory level.

 The joints are then raked out, removing all debris, carefully preparing the joints for the application of a specially designed lime mortar.
