Llyn Fawr

Llyn Fawr is a reservoir in a glacial cirque on the northern escarpment of the South Wales Coalfield uplands, overlooking the Vale of Neath and Cynon Valley [1]. The site is famous for the Llyn Fawr Hoard, an important collection of weapons and tools from the late Bronze Age and early Iron Age discovered during lake deepening work between 1909 and 1912 [1].
