The Castellania, also known as the Castellania Palace, is a former courthouse and prison in Valletta, Malta that currently houses the country's health ministry. It was built by the Order of St. John between 1757 and 1760, on the site of an earlier courthouse which had been built in 1572.

Maltese Baroque architecture is the form of Baroque architecture that developed in Malta during the 17th and 18th centuries, when the islands were under the rule of the Order of St. John. The Baroque style was introduced in Malta in the early 17th century, possibly by the Bolognese engineer Bontadino de Bontadini during the construction of the Wignacourt Aqueduct. The style became popular in the mid to late 17th century, and it reached its peak during the 18th century, when monumental Baroque structures such as Auberge de Castille were constructed.
