Three British atomic weapons tests were carried out at the Montebello Islands in 1952 and 1956. Concrete bunkers, monitoring stations, roads and scrap metal can still be found on some islands, and the former military operational headquarters can still be seen on the southern end of Hermite Island. As slightly elevated radiation levels still occur at test sites on Trimouille and Alpha islands, visitors should limit visits to one hour per day. Do not disturb the soil and do not handle or remove relics associated with the tests.
