The Roman name for the fort that lays beneath the castle at Brougham was Brocavvm. The Roman complex here consists of a major fort, a civilian settlement and a marching camp (situated about 400 yards North East of the fort and the castle) Both castle and fort sit next to the B6262, and just off the A66. The best views of the fort are to be had from the B road, as it almost exactly follows the course of the surviving Roman earthworks at the South side of the site.
The Eight Legion were known to have been stationed at the fort at Brougham, probably as early as 43AD when the Roman Emperor Claudius led his troops in the invasion of Britain.
A great Roman cemetery has also been found near the site. The cemetery was excavated before the building of the A66 which now completely covers the site.
On the whole, the Roman fort at Brougham has not been excavated to any great degree, so the historical and archaeological record of this large site are scarce.
Good views of the site can be seen from the roadside and also from walking around the castle. The earthworks are very well preserved all the way round with some of the ditches and embankments surviving to a height of around 6 feet in places!! Again, the Visit Cumbria web site has some excellent aerial views of the castle and the fort.
The whole site is open to the public, and managed by English Heritage. The access is such, that both the interior and the exterior of the castle can be walked....which obviously incorporates much of the Roman fort.Elslack (North Yorkshire)
