Lone Island, also called the island of Filfla, was possibly sacred to the Neolithic inhabitants of Malta, who built the temples of
Ħaġar Qim and
Mnajdra on the Maltese coast opposite the islet. The only known permanent structure on the island was a
chapel built inside a cave in 1343, which was destroyed by an
earthquake in 1856 that also sank part of the island. A map of Malta dating back to 1798 shows a fort, a lighthouse and a monastery with a chapel on Filfla. Until 1971 the
Royal Navy and
Royal Air Force used the island for target practice, and spent cartridges from these bombardments can still be found on Filfla today. Filfla was invoked in a territorial dispute over the
continental shelf between
Libya and Malta. The case was adjudicated by the
International Court of Justice in 1985 essentially by ignoring the islet from the calculations. A substantial piece of the island was eroded during
Storm Harry in January 2026, potentially threatening key
seabird habitat. ==Legends==
