Tas-Silġ is one of the most important archaeological sites in the Mediterranean and one of the least visited. The hilltop overlooking Marsaxlokk Bay holds the layered remains of a sanctuary occupied from the Neolithic right through to early Christian times — Megalithic temple stones, a Phoenician sanctuary to Astarte, Roman temple foundations, and the apse of an early Byzantine church, all on the same footprint.
The site is fenced and access is restricted; Heritage Malta runs occasional open days, typically in spring and autumn, and the visit requires booking in advance. If you can't get in, the views from the perimeter — over the salt pans, the bay, and the Delimara peninsula — are themselves worth the short walk up from the village.
