Gazebo Approximately 50 Metres South-East of East Hall

The gazebo, located approximately 50 metres south-east of East Hall, dates from the early 18th century and was built for Leonard Hartley. It is constructed of rubble with a pantile roof and stands two storeys high with one cell. The lower chamber features a 20th-century six-panel door, which leads up steps to a similar door for the first-floor room. The hipped roof is topped with an urn finial. On the left side, there are 20th-century windows with seven panes on the first floor.

Inside, the lower chamber has a barrel vault but lacks original features. The first-floor room has a simple fireplace occupying the entire west wall, with a panelled overmantel painted with a picture of flowers in a vase, flanked by Corinthian marble columns. The room also includes panelling and cupboards with doors of eight fielded panels, and a moulded chair rail around the walls, except on the south side where a window has been blocked up. The east window has fielded panel shutters. Notably, stolen copper was stored in the cellar of this building in 1742, as referenced in T R Hornshaw's "Copper Mining in Middleton Tyas" (1975).
