Cavallino Treporti - Monuments Pozzo di San Domenico In 1636 the woman marquise Beatrice Acquaviva of Aragon gave the Cavallinesi a work of public utility, a well dug in the square in front of the Mother Church. On it he had the stone statue of St. Dominic of Guzman erected, to which he was deeply devoted. It is said that from that well the women of the country drew pure and fresh spring water, while from the wells of the houses located behind the statue of the Saint came a thick and brackish water.
