The Chapel of St Matthew, popularly known as San Mattew Iż-Żgħir, literally meaning Saint Matthew the smaller, is a small medieval chapel located beside a larger church with the same name in an area known as il-Maqluba in Qrendi, Malta.

The only building to escape this tragedy was the chapel of St Matthew in which an old pious woman was at the moment of the engulfment.

However, most probably this large pit, a sinkhole, known as il-Maqluba was formed as a result of a violent storm that hit the island on November 14, 1343.

The small chapel of St Matthew was also mentioned in inquisitor Pietro Dusina's report during his apostolic visit to Malta in 1575.

Dusina describes that the chapel was equipped with all necessarily means to celebrate the divine office.
