According to
Wikipedia "Mdina (Maltese: L-Imdina), also known by its titles Città Vecchia or Città Notabile, is a fortified city in the Northern Region of Malta, which served as the island's capital from antiquity to the medieval period. The city is still confined within its walls, and has a population of just under 300, but it is contiguous with the town of Rabat, which takes its name from the Arabic word for suburb, and has a population of over 11,000 (as of March 2014)."
The police station is close to the main entrance gate into the city, and also one of the stopping points for horse drawn carriage tours.
