Current condition
Demolished / No longer exists
The belvedere, marked "lookout" on old maps, was on the top of a conical hill near to the Eyrie. This photo shows the Eyrie building in the foreground, and the belvedere on the hilltop at the top of the zig-zag staircase.
The belvedere no longer exists, as the hill is now the site of several radio towers, but the zig-zag staircase is still clear to see on modern maps.
