This old Portuguese fortified town is quite small and it doesn't take too long to walk through it and get a sense of the place. It's quite interesting in the way it was designed and the historical significance in indisputable. There are some nice views from the walls but, other than that, there's not a whole lot to see.
There were not many visitors at all when I came and I guess it's not the most popular place in the country. In fact, I didn't bother staying the night here and got the train up to Rabat afterwards (although that did get me in quite late).
