Sannat lies to the south of the Island and the name is probably derived from that of an Arab-Greek family that moved to Gozo from Sicily. This village boasts some important archaeologocal remains, namely L-Imramma Temple which is a primitive type prehistoric temple made up of a sort of an oval court with a series of more or less oval rooms to the north. Other interesting remains are three dolmens. These are found at Ta' Cenc which also happens to be the site of the highest cliffs in Gozo.
On 28 April 1688 Sannat was one of the first localities in Gozo to become a separate parish. It was establised as such by Bishop Davide Cocco-Palmeri. The building of the present parish church dedicated to St Margaret Martyr commenced on the site of a smaller church in 1718, but underwent several structural changes in the 1860s.
It was first consecrated on 16 October 1755 and then, after the structural changes, was consecrated again on 22 November 1868. It was raised to the Archipresbyteral status on 27 December 1893. The altar piece was painted by the famed local artist Stefano Erardi. The village feast of St. Margaret is celebrated each year around the third week of July.
