Għajnsielem is a municipality on the southeastern coast of the island of Gozo in Malta, including the entire island of Comino. It has a population of 3,200 residents, and is the first Gozitan village that greets the visitor on leaving Mġarr Harbour towards the Gozitan heartland. Its name originated from the water spring, around which in 1700, Grandmaster Perellos built an arcade containing public wash basins and fresh water spouts.
