Saint John's Cavalier () is a 16th-century cavalier in Valletta, Malta, which was built by the Order of St. John. It overlooks St. John's Bastion, a large obtuse-angled bastion forming part of the Valletta Land Front. St. John was one of nine planned cavaliers in the city, although eventually only two were built, the other one being the identical Saint James Cavalier. It was designed by the Italian military engineer Francesco Laparelli, while its construction was overseen by his Maltese assistant Girolamo Cassar. Read more on Wikipedia
