Yes, they're at the top of the hill, a folly associated with Hagley Hall I think.
They have a small castle and a Greek temple and of course an obelisk as well.
Check out the photo on the July 2007 Druidon, Jon.
The follies are on the west side of clent, with one or two on Wychbury Hill. Look out for the Obelisk on top of Wychbury about half a mile away, if you get chance.
