Called Castle at the Sea, which is the meaning of the Arabic Dar el-Bahar, is the main symbol of Safi, and the city's most photographed site. It is best viewed from the outside, but you will not get a good feeling of it until you actually enter.
The interior is very, very simple, which reflects the style of its period: early 16th century. Finding your way around is equally easy, but a nice reward for paying the standard entry fee of 10 dh are the marvellous views of the sea and the port of Safi.
