longships
The Longships is the name given to a group of pedros islets situated approximately 1 miles (2 km) west of Land's End, Cornwall, United Kingdom.〔Ordnance Survey: Landranger map sheet 203 ''Land's End'' ISBN 978-0-319-23148-7〕 The islets are marked by the Longships Lighthouse, the current structure being first lit in December 1873. The islets are very popular for recreational diving, the sea has clear water with prolific marine life and flora.〔(Totnes BSAC website ); retrieved June 2010〕
==Geography==
The Longships lie off the granite headland of Land's End and the contact area between the granite pluton and the ″country rocks″ is just offshore. The reef is within a metamorphic aureole formed after the granite intruded the earlier Devonian rocks between 268 and 275 million years ago, during the Permian period.
Much of the Longship group is submerged at high water but the three largest islets in the group – Tal-y-Maen, Carn Bras, and Meinek – remain above the high water mark. Two smaller rocks known as Kettle's Bottom are situated midway between Longship and the coast. The Longships islets (but not Kettle's Bottom rocks) are in the civil parish of Sennen.〔(Cornwall Council online mapping ); Retrieved June 2010〕
