Bere Island will host a number of events to mark the centenary of the US Navy being stationed on the island in 1917, over the weekend of Saturday July 1^st and Sunday July 2^nd. In 1917, while protecting the sea lanes off southern Ireland during World War One, American battleships and submarines from the US naval fleet anchored in the sheltered harbour off Bere Island, while in between patrols, where they would be protected by the extensive gun batteries on the island. American sailors came ashore to Rerrin Village to post mail home, and played baseball on a baseball diamond laid out at the British Admiralty Recreation Grounds in Rerrin.
