The tower of the castle of Troggy (Cas Troggy) was mentioned for the first time in documents in 1305 as newly created. It was erected by Roger Bigod III, Earl of Norfolk, as his hunting seat. However, it was planned to be strongly fortified (massive, thick walls, corner towers). It was probably abandoned shortly after the founder’s death, perhaps it was not even finished.
The castle was erected on a rectangular plan, occupying a flat area measuring approximately 27 by 42 meters, adjacent to the stream from the north. It was surrounded by a moat 15 meters wide on the west side and 10 meters wide on the north side, as well as curtains of the defensive wall, of which at least the southern one had a significant thickness of 2.7 meters above the battered plinth. The south-west and south-east corner of the walls were reinforced by cylindrical towers. The west tower stand on a 4-meter high hill, while the eastern one in front of the wall curtain had an unusual annex. The interiors of the towers had octagonal shapes with a diameter of up to 6 meters. The remains of a fireplace and two arrowslits are visible by the preserved southern part of the wall. Most likely, this part of the wall was a fragment of a residential building (hall).
The southern part of the wall and the relics of two corner towers have survived to this day. One of them has survived to a height of 6-7 meters, the other to about 3.5 meters. The monument is not protected, the area is densely overgrown with vegetation and neglected.
