Typical swarm locations
Collectors attend swarms in the older terraced streets on the valley sides above the town centre, in the sycamore and hawthorn scrub on the reclaimed tip margins east of the former steelworks, in the gorse and bramble fringe along the plateau edge above Cefn Golau, and in the eave and chimney voids of the 1930s and post-war council housing around Newtown and Briery Hill.
