The ramparts, built in the Spanish period, were modified by the famous Vauban himself. We can still admire the towers surrounding the city since the seventeenth century, as well as many other monuments: the tower of the Edifieur Baudoin, one of the oldest of all, Caesar Bastion built under Louis XIV the Green stronghold and the headquarters hospital, or the Fauroeulx door, the only one that did not suffer the Second World War and its demolition. The current castle, the Cernay, was built in the seventeenth century, replacing the twelfth century built by Baldwin IV of Hainaut. You can still see some remains of the original castle that served as a residence to Charles the Bold, as a gateway and a set of Romanesque cellars.

The castle, built in the 12th century by Baldwin IV of Hainaut, was the home of the Counts of Hainaut, also Counts of Holland and Zeeland. Its last sovereign was a woman who was born in the castle in 1401. Charles the Bold and then his daughter were the last sovereigns to reside there. It was then abandoned and almost completely abandoned from the 16th century. Of the prestigious castle of the Middle Ages, few remains remain: an entrance gate and a set of remarkable Romanesque cellars. The current large building called Cernay actually dates from 1681.

The Palace of Margaret of Burgundy in Le Quesnoy is a historic building that used to serve as the residence of Margaret of Burgundy, Duchess of Bavaria-Straubing and Countess of Hainaut, Holland, Zeeland and Oosterbant. Margaret of Burgundy (1374-1441) was the daughter of Philip the Bold of Burgundy and Margaret of Male. She married William VI of Holland in 1385, and after his death in 1417 she continued to live in Le Quesnoy as a dowager. The palace was one of her favorite residences, and she lived there with her daughter Jacoba of Bavaria. The palace is designed in a Renaissance style with strongly fortified walls and gateways strategically placed to protect the city. The building is built of brick and stone, which is typical of the military architecture of that period.
