Historic Landscape Characterisation
Natural upland lake in the central moorland area.
The area fell within the 19th-century tithe parish of Tiryrabad-isaf (Pentrefoelas).
Key historic landscape characteristics
The lake covers an area of about 0.3km2 at a height of about 380m above Ordnance Datum, mostly enclosed by higher ground, at the head of the Afon Alwen. Ancient waterlogged sediments at the base of the lake are of potential significance to the environmental and land use history of Mynydd Hiraethog. A boathouse and jetty were set up at Ty'n-llyn at the north end of the lake in the 1870s, approached by a track across the moorland from the direction of Pentrefoelas.
