Clock Tower, Glencorse Barracks, Penicuik

The Clock Tower at Glencorse Barracks in Penicuik dates from around 1810 and is a four-stage octagonal structure that originally housed prison cells and guard rooms. It is built from squared and coursed, stugged sandstone, featuring a base course, raised cills, and a cill band at the fourth stage.

The tower originally had four doors on alternate faces, but one door is now blocked and converted into a window, while two others have been brick-blocked internally. Each stage has rectangular, tablet-like windows that are now blocked with stone or brick, along with small ventilation louvres. These windows are located on alternate flanks and above each stage where doors were located at the ground level. The fourth stage windows, situated under the eaves, still show remnants of former bars. The clock, which is now modern, fills the oculi on four of the faces where the doors or former doors were located at ground level.

The tower is topped with a polygonal roof that is almost conical, flattened at the apex with a flagpole, and features overhanging eaves with exposed rafters.

Inside, there is a stone spiral staircase leading to the center, with cells radiating off from it. The interior also includes timber floors, boarded doors, and a water tank that is now suitably housed.
