Three large monoliths called Harold's Stones are located in a field on the eastern side of the B4293 to the south of Trellech. The stones are on slightly elevated ground close to running water and springs, which might be relevant to the choice of site. They are believed to date back to the Bronze Age. Such remains are rare in this part of Wales. They derive their name from a legend that they mark the spot at which three chieftains fell in battle with Harold Godwinson, who defeated the Welsh in Gwent in 1063. In another legend the stones were flung from Skirrid by the mythical Jack o' Kent in a competition with the Devil.
References:The Broch of Clickimin is a large and well preserved, though somewhat restored broch near Lerwick. Originally built on an island in Clickimin Loch (now increased in size by silting and drainage), it was approached by a stone causeway. The water-level in the loch was reduced in 1874, leaving the broch high and dry. The broch is situated within a walled enclosure and, unusually for brochs, features a large 'blockhouse' between the opening in the enclosure and the broch itself. Another unusual feature is a stone slab featuring sculptured footprints, located in the causeway which approached the site. Situated across the loch is the Clickimin Leisure Centre.
