Mnajdra is found in an isolated position on a rugged stretch of Malta’s southern coast overlooking the isle of Fifla. It is some 500m away from Ħaġar Qim Temples. It consists of three buildings facing a common oval forecourt. The first and oldest structure dates to the Ġgantija phase (3600 – 3200 BC). The second structure to be built was the South Temple, constructed in the early Tarxien phase (3150 – 2500 BC). The Central Temple, inserted between the other two, was the last to be built. Remains to the north-east and south of these buildings indicate that these three structures are only the best preserved of a larger complex.
The South Temple has its entrance set in a concave monumental facade and leads to two rooms, or apses. On the left-hand side, a decorated porthole doorway (a square-shaped opening cut in the centre of a stone block) leads into a small chamber. The apse to the right has a small rectangular opening which connects it to a chamber within the thickness of the walls accessible only from the rear of the building and a porthole doorway at the top of a small flight of stairs leading into another small chamber. Within the latter chamber is a small niche accessed through a small porthole slab set within a trilithon. This arrangement features on the Maltese 5, 2 and 1 euro cent coins. The four horizontal courses at the top of the walls in this area are perhaps the best indication of what the building’s roof would have looked like.
