A HISTORY OF BEDFORDSHIRE 
ton, Cotton End, Bassmead, Cardington and in many other places. 
Sometimes the moat forms a simple oblong; sometimes another moat 
divided the space into two. Many of these examples have exterior 
banks, which from their breadth and flatness apparently formed promen- 
ades. Sometimes another ditch is found outside these again, as at Riseley 
Old Domain and at Mavourn. In the latter the moat has a flat berm 
under the water line, and then suddenly drops to a depth of g feet, an 
ingenious device for embarrassing intruders. Most of these later works 
suggest enclosure rather than defence. 
A large number of works are found with the -éury in their names, 
and many of these stand on heights. Brogborough near Lidlington, a 
small stronghold originally of oval shape, is perched on a little hill-top, 
and has the remnant of a really mighty rampart turning round its south 
end, and also remains of a fine fosse. Here too are the remnants of an 
exterior rampart. 
Keysoe Park, or Berrystead, as it used to be called, is another 
example. This resembles Mr. Gould’s ‘ stirrup-shaped ’ works" in plan. 
The ditch was a formidable one, 40 to 50 feet across, with a low ram- 
part inside, of which considerable lengths remain, and a very large one

broad. ‘There is a narrow berm on both sides of the ditch, and the
