While visiting the Israel Akko would be the best choice for anyone who have ever read/watched/played games about crusaders. I'm not an exception here, so I went there with my aunt to dive into medieval world of the Middle east.
This photo I found in one of the museums in the Akko. It shows the old city from the bird sight. The museum itself is not very interesting though as it shows the jewish history and the mode of life in second half of 20th century.
Hospitalier fortress is one of the greatest places to visit in Akko. This fortress was excavated by archeologists for a longtime and some rooms in the fortress were burried under ground for 4 meters down.
