[1][2] Historically, the bay formed part of the nearby town of Żejtun,[3] which lies immediately uphill of the inlet.
The bay and Munxar point are popular with residents of Żejtun and other inland villages for swimming, hunting and bird-trapping.
[4] Some historians contend that St Thomas' Bay marks the true landfall of Paul the Apostle following his shipwreck on Malta.
[7] A large fortress, St Thomas tower was built at the tip of Il-Gżira ta' Wied il-Għajn in 1614 after an Ottoman fleet anchored in the bay and raided Żejtun.
The headland takes its name from a number of stacks, long since eroded into submerged reefs, which used to extend into the Mediterranean sea from Munxar point.
