Tas-Silġ is a rounded hilltop overlooking Marsaxlokk Bay. It is a multi-period sanctuary site covering all eras from Neolithic to the fourth century AD, and due to this it indicates to archaeologists several different layers of excavation.
The area was first inhabited when a temple was built in the Tarxien phase of Maltese prehistory, sometime around 3000 to 2500 BC. Few remains from the original temple can be seen, but the scatter of megaliths over the hill suggests that there was a large complex with at least 3 temples and possibly a village surrounding it. A D-shaped setting of large blocks that was part of the four-apsed temple still exists as it was later incorporated into the other buildings on the site. In the Bronze Age, the temple was probably converted into a settlement, as had been done in other sites such as Borġ in-Nadur.
In the deepest layer of deposits, archaeologists found various artifacts including pottery, lithics, and a standing fat lady. From the Bronze Age layer, some sherds, stone tools and pottery were found. Other evidence from the Bronze Age consists of the large amount of handiwork.
After the Phoenicians took over Malta in around 700 BC, they built a Punic temple to Astarte incorporating upstanding remains of the earlier temple. A forward extension was added to the curved facade, and a monumental doorway flanked with two pilasters and topped by a huge stone slab was built. The sanctuary"s importance eventually grew and a portico was added around 300 BC. Some parts of the temple, including a tower, might have been designed as a fortification to help defend it from possible invaders.
A threshold slab pierced by three libation holes that divided the eastern part of the temple and the western side, as well as a series of ashlar foundation walls for a platform built to the south of the main sanctuary still exist. Around this area, various remains were found including pottery, ash, animal bones, coins and shreds. Some of these shreds have votive inscriptions. It is claimed that the Cippi of Melqart might have originally been at the Tas-Silġ temple, but their origin is disputed.
In the Roman era, the Punic temple was converted into a sanctuary of Juno, which was the Roman equivalent to Astarte. In 70 BC, Cicero mentioned the temple in his Verrine Orations, in which he said that the temple was revered by everyone including pirates and Numidian princes, but the Roman Governor of Sicily had stolen some of its treasures. Some Roman material was discovered in various deposits around a well in the lower terrace of Tas-Silġ.
Large water storage areas under Tas-Silġ were recently found and mapped, and they probably date to the Punic or Roman eras.
Later on, in the 4th or 5th centuries AD, a Byzantine monastery were built over the remains of the previous temples. The church had a central nave separated from the aisles by two rows of columns, and a small baptismal font was constructed in what was originally the megalithic temple. Some remains of sculpture were found, including a worn female marble head and an ivory capital with a hanging palmette. Pottery from this period was also found, including amphorae and locally made plates and other items.
During the Byzantine period, it may be that the fat lady was deliberately defaced and buried in a hollow.
In the 8th century, defensive walls were hastily built around the monastery at Tas-Silġ.
The monastery was abandoned soon after the Arabs occupied Malta in 870 AD. The site was turned into a quarry and stones from the original structure were removed. In the medieval period farms were built on the area, and rubble walls from this era still exist. The whole site was buried under a metre of soil before being excavated.
References:Saint-Georges de Boscherville Abbey is a former Benedictine abbey. It was founded in about 1113 by Guillaume de Tancarville on the site of an earlier establishment of secular canons and settled by monks from the Abbey of Saint-Evroul. The abbey church made of Caumont stone was erected from 1113 to 1140. The Norman builders aimed to have very well-lit naves and they did this by means of tall, large windows, initially made possible by a wooden ceiling, which prevented uplift, although this was replaced by a Gothic vault in the 13th century. The chapter room was built after the abbey church and dates from the last quarter of the 12th century.
The arrival of the Maurist monks in 1659, after the disasters of the Wars of Religion, helped to get the abbey back on a firmer spiritual, architectural and economic footing. They erected a large monastic building one wing of which fitted tightly around the chapter house (which was otherwise left as it was).
