This Magisterial Palace was built over a large cave that featured a sculptured mermaid on its ceiling, and is thus referred to as Villa Sirena. During the summer months, boats sheltered in the cave and the garden was surrounded by a pergola that supported a canopy which was overflowed with vines. In 1590 the Order passed this palace to the Knight Vincenzo Caraffa, a relative of Grandmaster Carafa (1680-90). From records dated 19^th August 1882, it appears that by then the Villa had become known as Villa Davies and was used as a venue for theatrical performances – thus retaining its original function as a haven for leisurely pursuits.
