The buried and earthwork remains of the manorial moat and fishpond at Huddington Court. The moat island is rectangular, measuring some 80 metres by 40 metres, and is defined by a substantial moat which remains water-filled. The moat measures up to 3 metres deep and 10 metres wide. The island is generally level and landscaped, and no traces of structures relating to medieval occupation are evident, although they are expected to survive as buried features. At the centre of the island is an early 16th century house which was altered circa 1584. The house is timber-framed with painted brick and rendered infill on a stone plinth with plain tiled roofs. A rear wing was added in the early 17th century. Huddington Court was, at the time of the Gunpowder Plot, the family home of the Wyntour family and is believed to be the place where Robert Catesby, a cousin of the Wyntours, first hatched the plot in 1604. On November 6th 1605 the conspirators met at Huddington to hear their final mass together. Robert, Thomas and John Wyntour were all executed for their part in the conspiracy, as was Father Garnet who was implicated because of the use of Huddington as the headquarters of the Jesuit Mission in England. Parallel with the moats southern arm, and 200 metres to the south of the moat, is situated a rectangular ditch 60 metres long by 10 metres wide by 3 metres deep. This waterlogged ditch is believed to represent the southern arm of a second concentric moated enclosure which enclosed the surviving moat. To the north west of the extant surviving moat is a large medieval fishpond which formed a western extension of the northern arm of the outer moat. The moat is Scheduled and the house is Listed Grade I.
