The Battle of Ronas Voe was a naval engagement between the English Royal Navy and the Dutch East India ship Wapen van Rotterdam on 14 March 1674 in Ronas Voe, Shetland as part of the Third Anglo-Dutch War. Having occurred 23 days after the signing of the Treaty of Westminster, it is likely to have been the final battle of the Third Anglo-Dutch War. An unknown number of up to 300 of the ship's crew were killed in the battle and were buried nearby in Heylor. A modern memorial to the Dutch crew is erected where they are believed to be buried, bearing the inscription "The Hollanders' Graves".
