Penhaligon House, Princes Street Front

Penhaligon House, located on Prince's Street, is a large town house that has been converted into a bank. It was built in the early 18th century for a member of the Gregor family. The building suffered partial destruction due to a fire in 1923 but underwent extensive repairs in the late 1980s. It features local rubble walls and a hipped dry Delabole slate roof with projecting eaves and pierced clay ridge tiles. The rectangular plan includes two large rooms at the front, flanking a central entrance hall, and the building stands three storeys high with a symmetrical five-window range.

The exterior includes a plinth and a central stuccoed Tuscan doorway with engaged columns and a moulded entablature, leading to a wide six-panel door with fielded panels. The windows have been altered in the 18th century and now feature wide 20th-century tripartite horned sashes with glazing bars, with rendering above the second-floor windows. Inside, the restored mid-18th century plaster ceilings in the entrance hall and the right-hand room boast carved and moulded modillioned cornices, with one ceiling decorated with arabesques in the corners and center.

Historically, it is said that the poet Alfred Lord Tennyson stayed here, befriending the Cornish poet Henry Sewell Stokes, during which time he wrote "In Memoriam."
