Mnajdra is a megalithic temple complex built around the fourth millennium BCE; the Megalithic Temples of Malta are among the most ancient religious sites on Earth. In 1992 UNESCO recognized the Mnajdra complex and four other Maltese megalithic structures as UNESCO World Heritage Sites. In 2009 work was completed on a protective tent.
Mnajdra is made of coralline limestone, which is much harder than the soft globigerina limestone of Ħaġar Qim. The main structural systems used in the temples are corbelling with smaller stones, and post-and-lintel construction using large slabs of limestone.
The cloverleaf plan of Mnajdra appears more regular than that of Ħagar Qim, and seems reminiscent of the earlier complex at Ggantija. The prehistoric structure consists of three conjoined but not connected temples: the upper, middle and lower.
The upper temple is the oldest structure in the Mnajdra complex and dates to the Ggantija phase (3600-3200 BC). It is a three-apsed building, the doorway of which is formed by a hole cut into a large piece of limestone set upright, a type of construction typical of other megalithic doorways in Malta. This temple appears originally to have had a vaulted ceiling, but only the base of the ceiling now remain on top of the walls. The pillar-stones were decorated with pitmarks drilled in horizontal rows on the inner surface.
The middle temple was built in the late Tarxien phase (3150 – 2500 BC) and, in fact, is the most recent structure. It is formed of slabs topped by horizontal courses.
The lowest temple, built in the early Tarxien phase, is the most impressive and possibly the best example of Maltese megalithic architecture. It has a large forecourt containing stone benches, an entrance passage covered by horizontal slabs, one of which has survived, and the remains of a possibly domed roof. The temple is decorated with spiral carvings and indentations, and pierced by windows, some into smaller rooms and one onto an arrangement of stones.
The lowest temple is astronomically aligned and thus was probably used as an astronomical observation and/or calendrical site. On the vernal and the autumnal equinox sunlight passes through the main doorway and lights up the major axis. On the solstices sunlight illuminates the edges of megaliths to the left and right of this doorway.
References:The Temple of Edfu is one of the best preserved ancient shrines in Egypt. It was built in the Ptolemaic Kingdom between 237 and 57 BC.
Edfu was one of several temples built during the Ptolemaic Kingdom, including the Dendera Temple complex, Esna, the Temple of Kom Ombo, and Philae. Its size reflects the relative prosperity of the time. The present temple initially consisted of a pillared hall, two transverse halls, and a barque sanctuary surrounded by chapels. The building was started during the reign of Ptolemy III Euergetes and completed in 57 BC under Ptolemy XII Auletes. It was built on the site of an earlier, smaller temple also dedicated to Horus, although the previous structure was oriented east–west rather than north–south as in the present site.
