An artificial cave in an upper cliff on the Ras il-Wardija, the extreme south-west corner of the island, was cut in Phoenician times as a religious sanctuary and dug by an Italian team in the 1960s. The attribution to the nymphs is an improbable one, but the site is certainly in a very dramatic natural position.
