The Pen Mill Hotel

The Pen Mill Hotel is an inn that is believed to have been built around 1810, with significant remodeling occurring around 1855 in anticipation of the railway's arrival. The building is constructed from ham stone ashlar and features a hipped roof covered with Welsh slate. It stands three stories tall and has three bays on both the road-facing southwest elevation and the side southeast elevation.

The central entrance consists of double doors with three panels and is topped by a cast iron fanlight that is diagonally glazed, all set within a large, plain Doric porch that projects boldly and includes a full entablature. The ground and first-floor windows are 12-pane sashes, while the second floor, which may have been added around 1855, features a low plinth and rusticated quoins. The southwest return elevation is similar, but the central doorway has been blocked and a window has been inserted.

On the left-hand side, there is a smaller two-story extension with three bays, also made of ashlar, which has a double roof with a coped gable and may have originally been a separate house. This extension has a central six-panel door with a projecting pedimented porch and two 2-light timber casement windows on each level. The interior of the hotel has been extensively remodeled around 1970, although some west ceiling cornices remain. The one-story section to the northwest and the buildings at the rear are also of interest.
