Chartist Cave (or sometimes Chartist's or Chartists' Cave) is a culturally significant cave on Mynydd Llangynidr in southern Powys, Wales. It lies around 2.5km north-northeast of the village of Trefil at an elevation of about 550m at OS grid reference SO 127152 (51.8286 degrees North, 3.2672 degrees West). The entrance is a broad arch formed of Twrch Sandstone ('Millstone Grit') which overlies the Carboniferous Limestone immediately beneath.
The cave is also known by two Welsh names; Ogof Fawr (the 'Big Cave') and earlier as Tylles Fawr (the 'Great Hole'). The more commonly used modern name derives from 1839 when Chartist rebels used the cave to stockpile weapons in advance of their march on Newport in November of that year. There is a plaque at the entrance commemorating the actions of the Chartists.
Digging by a caving club in 1969 led to the discovery of a passage dropping to a lower chamber with many passages leading off from it. Its known length is 440m but it must form a part of a much more extensive cave system under these moors.
It forms a part of the Mynydd Llangynidr site of special scientific interest designated by the Countryside Council for Wales for its karstic landscape in August 2012.[1]
