Castello Dei Baroni is a 20th-century residence in Wardija, Malta. In the 18th-century, during the magistracy of Grand Master Emmanuel de Rohan-Polduc, a rural building was constructed on site. The Montalto family owned the whereabouts of its site in the 20th-century, and built the Castello Dei Baroni, incorporating the old structure. It was then purchased by Adrian Busietta and Maria Caruana, when it was renovated into a mock castle and given its name. It has since then mainly served as a wedding reception.
