Ruins of Piercefield House, Right Hand or East Pavilion

The ruins of Piercefield House's Right Hand or East Pavilion date back to the early 19th century. This pavilion is constructed from Bath limestone ashlar with internal brick walls, although the roof is not visible. Only the front, or south elevation, is clearly seen. The structure is designed in a temple style, featuring a tetrastyle front with Roman Doric half columns that support a full entablature and pediment. The only opening is a large square-headed one in the center, which has a moulded architrave and keyed head. The outer bays of the pavilion include apsed niches intended for statues. Above these niches, there are carved panels made of Portland stone set into the head of each bay, situated above a plat band.

Originally, the pavilion was connected on the left side to the main block of Piercefield House, which has since been demolished. The scarring on the wall suggests that this connection was likely a corridor with a gabled roof leading to a small door. Historical photographs depict this area as a five-bay arcade with a pitched roof, and they also show that the pediment once held three statues, while the roof featured a central lantern.

The pavilion appears to have been a top-lit single room, but the interior now retains no features except for a fireplace opening on the north wall. In 1819, the Drawing Room, Dining Room, and Saloon with the main staircase were located in the central block, while the attached pavilions served as the Library and Music Room.
