Founded in 1889, this abbey was built in the Gothic style. Listed as a Historic Monument, it consists of several buildings, including two castles. Today, it is home to around twenty Benedictine nuns of all ages. The monastery is partially open to the public: the abbey church, parlor, and shop are accessible.

The Porte d'Aire in Cassel is one of the historic city gates that is part of the old defensive wall of the city. This gate is known for its Gothic architecture and is an important historical monument. The Porte d'Aire is located on the southern side of the city and is one of the four gates that are still preserved from the medieval city walls. The gate has a characteristic serrated edge and is decorated with a carved coat of arms and a red inscription.

Antoine Demoitié was a Belgian cyclist who tragically died during the Gent-Wevelgem cycling race in 2016. He fell after 115 kilometers of racing and was then hit by a motorcycle. Demoitié was taken to the hospital in Lille in critical condition, where he later died of his injuries. A memorial stone has been erected in memory of Antoine Demoitié in Sainte-Marie-Cappel.
