Ix-Xewkija lays half way between Mġarr Harbour and ir-Rabat and is best known for its awesome rotunda, the circular church at the centre of the village. Gozo’s largest church, its dome is a distinctive landmark visible across much of the island. It is claimed to be the third largest unsupported dome in the world (28m in diameter and 75m tall), was built in the 20th century and is dedicated to St. John the Baptist.
