Davaar Island, situated at the mouth of Campbeltown Loch on the eastern coast of Kintyre in Argyll and Bute, Scotland, is a tidal island accessible via a natural shingle causeway near Campbeltown during low tide. In 1854, a lighthouse was constructed on the northern end of the island. It was automated in 1983. Presently, Davaar Island is only inhabited by caretakers and sheep. During the 1960s, local stamps were issued for Davaar Island, serving the purpose of allowing visitors to have their mail posted there and carried by the boatman to the nearest General Post Office Post Box in Campbeltown on the mainland. The boatman service ceased operations in the early 1970s. The postage rates for Davaar Island were double those of the UK (Source: Davaar Island stamps). Thus, post sent from Davaar had both UK and Davaar stamps, see for example these covers with Salvation Army stamps on the frontside and Davaar stamps on the backside.
