Description

The Jamaica Inn is a public house dating to the late 18th century. It is located in Altarnun. Originally, the building likely comprised two rooms with a cross or through passage, heated by end stacks. In the 19th century, it was extended with two further rooms on either side; the right-hand room had a fireplace backing onto the original right-hand end fireplace. Later additions include a rear range constructed in the 19th and 20th centuries. Stables, which connect to the front right corner and project as a wing to the right, have been converted into domestic use, with a shop on the ground floor. The front façade is symmetrical, featuring a 1:3:1 window arrangement with 20th-century casement windows. A central 20th-century gabled porch shelters a 20th-century door, flanked by two 2-light casements on each side. Five similar casements are present on the first floor. Internally, the central range's internal partitions have been removed, and fireplaces retain roughly cut granite lintels. The inn is closely associated with Daphne du Maurier’s novel of the same name, and its popularity grew as a result of the book’s success.
