The Templars were a military-monastic order who aided pilgrims and the ailing coming from Europe to visit the holy sites of the Land of Israel.
The Templars first settled in Jerusalem, on the Temple Mount, hence their name, “the Templars”, the guardians of the Temple. Following the conquest of Jerusalem by Salah Al-Din in 1187, the Templars made their home in Acre.
The tunnel is 350 meters long and it extends from the Templars fortress in the west to the city’s port in the east. In the past it served as a strategic underground passageway that connected the palace to the port.
