URPoint Details
Llyn Llywenan (English: Yew Tree Lake) is a lake in western Anglesey, just over 1 kilometre (0.6 mi) north of the village of Bodedern and 9 kilometres (5.6 mi) east of the town of Holyhead. At a maximum length of 1.1 kilometres (0.7 mi) and breath of 0.4 kilometres (0.2 mi) it has a surface area of only 0.4 square kilometres (0.2 sq mi). This makes it the largest natural lake on the island—both Llyn Alaw and Llyn Cefni are larger but are man-made.
The lake, a Site of Special Scientific Interest, is situated 34 metres (112 ft) above mean sea level and has some rare aquatic plants, as well as the fact that the lake is very shallow and could in the next hundred years or so be filled with silt. There is a small, rather featureless, island in the middle of the southern section of the lake which is roughly 35 metres (115 ft) across.
There are two Neolithic burial mounds immediately to the south of the lake, one of which is quite complete.
