Oh jeez, they named a fort after Jesus? Well unlike the prophet the fort is not special, at all. So the unique points are that it was numero uno European (Portuguese) fort in the area of this style, second being that it was taken over by the Omanis. You can get around the entire fort within 20 minutes as it's so small. If you want to hire a guide they will approach you as you get to the entrance already and the ticket check lady asked me again as I entered. I think there are only two places that they would be useful. 1. The great wall painting and I would say that IS the best about the fort if not for it being remade in the 60s. Here there would be explanations to appreciate it more. Second would be arch passage and rooms below because by itself it's nothing to look at and I overheard the guides chat about it a lot. The main barracks are currently under renovation so I think they will add a lot to see later. There is also a small Omani museum but it's not really related to the fort (and talks about heritage sites in that country instead) as well as a large whale bone collection which again doesn't apply to the fort.

Even though I had all morning planned for the sightseeing it was already done within an hour. Can't really recommend it.
