Mdina is the old capital of Malta, although
Valletta has been the contemporary capital city ever since.
Mdina is a medieval town with narrow, quiet streets, located in the center of the island. It is also known as the "Silent City" because no cars are allowed with the exception of limited number of residents, emergency vehicles, wedding cars and hearses. However, it can be a bit crowded with tourists at times, which makes is less silent than I thought it would be after reading all those silent announcements.
Nevertheless, Mdina is unique and very historical, rendering beautiful views of the island.
