Tyn Llan (Harp Hotel)

This two-storey building, known as Tyn Llan (Harp Hotel), is an example of a roughly U-shaped building constructed in a simple classical style. It dates to the 18th century. A set-back range is attached at a right angle to the right side, and it is partially hidden from the road by a lower stable range that forms a small service courtyard. The exterior is constructed of irregularly coursed rubble stone with large quoins, slate-stone lintels, and reddish-brown brick window dressings to the centre and left bays. The roof is slate with eaves soffits and hips that follow the angles of the projecting ranges.

The building has a 3:3:3 bay facade, with a central recessed section featuring a full-length verandah. The outer bays project with canted ends. All windows are unhorned sashes with slate sills, 12-paned on the ground floor and 9-paned on the first floor. Some upper windows in the projecting ranges and centre range are dummies with painted glazing bars; a dummy window is also on the ground floor of the left projecting range. A slate panel in the ground-floor centre of the right projecting range bears an inscription in Welsh and English, praising the inn's hospitality but cautioning against drunkenness. The central entrance has a ribbed and boarded door, flanked by sash windows, all sheltered by a slate-roofed verandah supported on cast-iron columns. A prominent stuccoed and panelled ridge stack is located on the left projecting range, with another behind; rebuilt red brick ridge stacks are present on the centre and right projecting ranges. The right return of the right projecting range has a small 12-paned horizontal sliding sash window on the first floor and a 12-paned sash window on the ground floor. The stable range has deep projecting verges to the gable ends and a central gable with a brick roundel facing the road. The left return of the left projecting range has three bays with sash windows, alongside a single-storey addition to the rear.

The interior retains plaster finishes on the walls and ceilings, along with 6-panel doors and partly rebuilt open fireplaces, some featuring 19th-century cast-iron grates.
