This unusual house stands high on a spur of the Cotswolds. It was built as a four-storey hunting lodge in c. 1550, but reworked by James Wyatt in the 1790’s. Wyatt also updated a second block added in the late 17th century.
Inside, there are interesting rooms and contents on three floors. Much of what is on display was collected by a late tenant who occupied the house for many years. Some features of the interior date from the Tudor era. There are fine views from the upper windows.
IIRC the basement floor is also partly open.
Outside, there are formal gardens laid out by the late tenant.
I visited Newark Park on a detour after finding that somewhere else at which I had intended to stop was closed that day. However I liked Newark Park and found it an interesting visit.
