First of all, let's take a look at the monumental gatehouse dating from the late 15th century, protecting the castle's former medieval walls. It is the only remaining vestige of this enclosure, which once had seven gates (but only five in 1645), and which in 1595 escaped the vengeful hammer of the demolishers from Lange. This gateway, once closed by a drawbridge whose rebate and traces of its lifting system can still be seen, was once protected by a bretèche (no longer in existence) and a fire hydrant that can still be seen. The pedestrian passageway on the left was converted late in life to serve as a prison, and its crown was rebuilt in 1857 by the Langrois architect Henri Brocard.
Note the large 18th-century calvary on the left of the square, with its cylindrical base surmounted by a fluted column supporting a Corinthian capital. It appears to have been built by a certain N. Jacob, a burgher from Montsaugeon (known in 1562), as can be seen from the coat of arms surmounted by his name, displayed halfway up the shaft.
