The Crusader Wall
The undercroft, partly excavated in the bedrock, consists of a wide vaulted corridor that gave access to two side chambers used for the storage of valuable goods.
To the east of the undercroft runs this outer corridor, between the first and second castle walls, where archaeologists have identified an ancient Roman wall at the very base of the structures.
It is possible that the construction of the castle, known at the time as Montréal and completed according to written sources in eighteen days by King Baldwin 1st, was facilitated by the preexistence of Roman-era fortifications.
