de Wignacourt and around the same time when the fortifications were being reconstructed. This chapel is annexed to the cathedral. Other chapels dedicated to Saint Lawrence and Our Saviour existed within the Cittadella during the medieval period. These were deconsecrated following Inquisitor Pietro Dusina's visit in 1575, and no remains have survived today. Other buildings The main square of the Cittadella, which is known as Pjazza tal-Katidral (Cathedral Square), contains the Law Courts. These are housed in two buildings, one of which was purpose-built as a courthouse, and another, which was formerly the Governor's Palace, built in the early 17th century. Opposite the Governor's Palace is the Bishop's Palace. Adjoining the Chapel of St. Joseph, there is a residential palace that was built by Bishop Baldassare Cagliares in 1620. A fountain against a wall is a commemoration of the naming of the city as Victoria, the then Queen of Great Britain, on 10 June 1887. The following buildings are now open to the public as museums: The Old Prison, located behind the Law Courts, which was used as a prison from the 16th century to 1962. It contains well-preserved prison cells and other exhibitions. The Gozo Nature Museum, which is dedicated to Gozo's geography, geology and natural science. It is located within a group of 17th-century houses which, at times, had been used as an inn. The Gozo Museum of Archaeology, which is dedicated to Gozitan history from the prehistoric to medieval periods, is located within a 17th-century house that was originally known as Casa Bondi. Gran Castello Historic House, which is dedicated to Gozitan folklore. It is housed in a cluster of early 16th-century houses. These four museums are run by Heritage Malta.
