Jersey Round Tower

Jersey is a heavily fortified island with coastal fortifications that date from different periods such as the English Civil War, the Napoleonic Wars, and Nazi Germany's occupation of the Channel Islands. The fortifications include castles, forts, towers, Martello towers, artillery batteries, and seawalls. Not infrequently, fortifications from one period are built on the site of earlier fortifications, or very near them, geography having remained the same even when firepower increased.

As of 2013, some of the fortifications are museums, or holiday accommodation, private homes, and event and sport venues. Most are under the control of the States of Jersey, Jersey Heritage, the National Trust for Jersey, and the Channel Islands Occupation Society.

Coastal towers stand all along the coast of the island. The British built 22 round towers, one similar square tower, and eight Martello towers towards the end of the 18th Century and in the early to mid-19th Century, but now only 24 remain, including seven of the Martellos.

On 28 May 1778 the Governor of Jersey, Field Marshal Henry Seymour Conway, submitted plans to Lord Weymouth for the construction of 30 coastal towers to forestall, or at least impede French incursions on the island. King George III granted approval and funding on 5 July 1778.
