Considering that there aren't a lot of interesting places to visit in Alexandria, it's definitely worth a visit, there's nothing super interesting here, but it's clean, there are a lot of interesting places inside the fort, and a good view of the city
It's beautiful, though rather boring.
This is the place where the Lighthouse of Alexandria stood, destroyed by an earthquake.
This citadel was built on the site of the lighthouse.
Several walls surround the building, with passageways between them.
You can go into the building itself and walk around the floors.
