Description
Cissys is a house, likely dating from the 18th century. It is constructed of stone rubble with large granite quoins, and has a slate roof with gable ends. A stone rubble end stack is located on the left side. The house was originally planned with a single room and an entrance on the right, and is heated by the end stack. The exterior presents a symmetrical two-window front. The entrance is on the right, and there is a 19th-century three-light casement window to the left, both with timber lintels. Two 19th-century two-light casement windows are located on the first floor. The interior has not been inspected.
