Between 1723 and 1733, a new star fort was built on the island by the Portuguese Grand Master António Manoel de Vilhena. The fort was called Fort Manoel after the Grand Master, and the island was renamed at this point. The fort is considered a typical example of 18th century military engineering, and its original plans are attributed to René Jacob de Tigné, and are said to have been modified by his friend and colleague Charles François de Mondion, who is buried in a crypt beneath Fort Manoel. The Fort has a magnificent quadrangle, parade ground and arcade, and once housed a baroque chapel dedicated to St. Anthony of Padua, under the direct command of the Order.
