Period: gothic

The original gatehouse, marking the entry to the monastic precinct, was constructed in the fourteenth century as part of the fortifications. The original gate had a portcullis and two passages, a smaller one for pedestrians, and a larger one for cart traffic. A wet moat could originally be traversed only by a drawbridge.

In the 17th century, the gate complex was transformed into a ceremonial passageway. The outer tower was extended and joined to the chatelet. The drawbridge was suppressed, and the moat was covered by two tunnel vaults supporting a new roadway to the chatelet.
