One of two linked terraced Garden Buildings on N.Side of Park at Castle Hall

This listing describes one of two linked terraced garden buildings located on the north side of the park at Castle Hall. The two surviving structures are arranged in sequence, with the first being a large vaulted sub-structure that overlooks a fish-pond. This part features a plain rubble front with three arches and rough voussoirs. Inside, it has three and a half bays by two bays in depth, with a groin-vaulted ceiling supported by plain square piers and blank arches on the rear wall. The inner west door has an eroded stucco doorcase, and in front of the building, there is a pond with a small dock for skiffs.

The building to the west, referred to as the pinery although this is not clearly evidenced, is heavily overgrown and consists of three plus six bays. It is roofless but was formerly topped with a monopitch roof facing north towards the rear retaining wall. Constructed of rubble stone, it features classical details, including remnants of a cornice that steps up at the eastern three-bay section. The upper level has small lunettes, and the main front is divided by raking buttresses that separate round-arched recessed panels, which contain large cambered-headed windows with rough stone voussoirs. The arched doorway in the west end wall leads to the interior, which has a sunk water tank in the floor with runnels and a possible boiler chamber.
