Flat Holm

Flat Holm (Welsh: Ynys Echni) is a limestone island lying in the Bristol Channel approximately 6 km (4 mi) from Lavernock Point in the Vale of Glamorgan (though it forms part of Cardiff). It includes the most southerly point of Wales. The island has a long history of occupation, dating at least from Anglo-Saxon and Viking age. Religious uses include visits by disciples of Saint Cadoc in the 6th century, and in 1835 it was the site of the foundation of the Bristol Channel Mission, which later became the Mission to Seafarers.
