Aka Fortress The most amazing thing in the whole city of Akka is the Aka Fortress, which is the prison here. The square traces on the wall seem to tell people that there are countless prisoners at the time. However, the prison environment is as cold as a mouse hole. A crusader who makes sugar in the Crusaders. It is also a medical facility. It is equivalent to a battlefield hospital. Its name is the Hausbida Fortress Knight Hall. It is the guarantee of war and is the key. And the Templar with it defends the country, a strategically important underground fortress.
