Cosmeston Medieval Village is a "living history" medieval village near Lavernock in the Vale of Glamorgan not far from Penarth and Cardiff in south Wales. Based upon remains discovered during a 1980s archaeological dig in the grounds of Cosmeston Lakes Country Park, it is a re-creation of 14th century peasant life in Wales in the Middle Ages.
The reconstructed village regularly plays host to groups of reenactors, who camp in authentic tents around the outskirts of the village, and perform displays of historical combat for the public.
Cosmeston was also used as one of the filming locations for the BBC TV drama series Merlin, broadcast in autumn 2008.
