Worthy of note is the private chapel in San Anton Palace, dating back to Knight Fra Antoine de Paule, a Frenchman from Provence, who was elected Grand Master of the Order of St. John in 1623. The Chapel is dedicated to the Madonna del Pilar. Its vault is decorated with the coats-of-arms of Grandmasters Antoine Manoel de Vilhena, Manoel Pinto de Fonseca and Emanuel de Rohan-Polduc. The chapel is similar to the contemporary churches of the first half of the 17th century found in towns and villages. The altar is set in a deep chancel separated from the nave by two pilasters which carry the last arched rib of the vault.
