Francesco Zerafa in the context of "Castellania (Valletta)"

The Castellania (Maltese: Il-Kastellanija; Italian: La Castellania), also known as the Castellania Palace (Maltese: Il-Palazz Kastellanja; Italian: Palazzo Castellania), 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.

The building was built in the Baroque style to design of the architect Francesco Zerafa, and completed by Giuseppe Bonici. It is a prominent building in Merchants Street, having an ornate façade with an elaborate marble centrepiece. Features of the interior include former court halls, a chapel, prison cells, a statue of Lady Justice at the main staircase and an ornate fountain in the courtyard.
