So what's special about his house? According to a sign erected next to this house, the building is described as having, "No particular features except for the fact that this house is believed to be at the centre of Malta." Now if Malta is approximately in the middle of the Mediterranean Sea, give or take a few millimetres ;) then this house must really have a central position!
this house was originally a farmhouse built as far away as possible from the coast which during the time of the Knights were prone to many pirate attacks.
