The Montebello Islands, also rendered as the Monte Bello Islands, are an archipelago of around 174 small islands (about 92 of which are named) lying 20 km (12 mi) north of Barrow Island and 130 km (81 mi) off the Pilbara coast of north-western Australia. The islands form a marine conservation reserve of 58,331 ha (144,139 acres) administered by the Western Australian Department of Environment and Conservation. The islands were the site of three British atmospheric nuclear weapons tests in 1952 and 1956.[1]
