The Port Mahon Inn

The Port Mahon Inn is an early 18th-century building located on St Clement's Street. It is a three-storey structure built of rubble on a moulded stone plinth, featuring cellars and two attic dormers beneath a Welsh slate roof. The north elevation, facing the road, has six steps leading up to the front doorway, which is topped with a semi-circular stone head. On the ground floor, there are two plain sash windows set in stone frames. The first floor features two three-light 18th-century sash windows with a blind semi-circular headed window between them. Above this, there is another window that breaks through the eaves, adorned with a pediment and scrolled sides. A stone band runs above the first-floor windows, and the building has two brick chimney stacks. The attic dormers contain 19th-century sash windows.

At the southeast corner, there is a stone extension or wing with a hipped Welsh slate roof and 18th-century style sash windows, complete with stone frames, cills, and architraves. The south side has a gabled staircase projection, while the west side features modern one-storey additions. Inside, the building has been modernized but retains some original fireplaces. A drawing of the inn from the early 19th century by J.C. Buckler can be found in the Bodleian Library.
