Fort Tas-Silġ (formerly written as Fort Ta Silc, Maltese: Il-Fortizza tas-Silġ) is a polygonal fort in Marsaxlokk, Malta. It was built between 1879 and 1883 by the British on high ground at the shoreward end of Delimara Point, above il-Ħofra-ż-Żgħira. Its primary function was as a fire control point controlling the massed guns of Fort Delimara on the headland below. Approximately 300 metres north of Fort Tas-Silġ is the Saint Paul's Battery, a much smaller polygonal style fortification, that is in much worse repair.
