The elliptical tower was mainly used for artillery. It has 16 openings to shoot from, called “couleuvrinières”. They are named after small portable canons called « couleuvrines”. What makes this tower special is that its « couleuvrinières » have double openings, which enlarge the shooting angle without weakening the building’s structure.
The ground floor and other floors are not adjoining. The floors above ground level used to overlook the residence directly. Since the residence no longer exists, a wooden stairway was built outdoors to give access to door on the first. Inside, there is a room with two bay windows. Beneath these openings, there are two « couleuvrinières ». A spiral wooden staircase leads to the second floor, with a room identical to the one on the first floor. There are traces of ochre circles painted on the wall.
The stairway leads up to the third floor and its artillery platform. Its circular shape was convenient for pointing canons in different directions.
There were machicolations on the top of the tower. You can still see a few traces of these today.
