Hagar Qim

This Copper Age temple was originally built about 2,700 BC but during the same period it underwent several modifications. For some unknown reason the axis of the first temple was altered and the temple itself was several times extended.
The kind of stone used in the building of this temple (Globigerina Limestone) is rather soft and relatively simple to work; possibly for this reason there are several "porthole" openings in Hagar Qim.
A monolith on the outside of the temple wall has been tentatively interpreted as evidence of phallic worship.
A pillar "altar" with an unusual palm frond decorative carving has been found in this temple, but not in any other; it is possible that this pillar was not originally part of the temple furniture and was placed there at a later date.
