Pruntrut Castle (French: Château de Porrentruy) is a castle complex above the town of Pruntrut in the Swiss canton of Jura. The hilltop castle originally dates back to the 13th century and was built by the Counts of Montbéliard. The Réfus Tower next to the castle building was probably built around 1271. From 1524 to 1792 it served as the residence of the prince-bishops of Basel. Structurally, the castle is in the same condition as it was at that time. It has been the seat of the judicial authorities of the canton of Jura since 1979. The facility can be visited on weekdays.

The Faux d'Enson observation tower is a 9 meter high concrete tower with metal stairs, built in 1989 by the Jura section of the Swiss Alpine Club. It is located at an altitude of 927 meters, at the summit of the Faux d'Enson mountain, which is part of the Mont-Terri range. From the tower, you enjoy a breathtaking view of the whole of Ajoie, as well as the border between France and Switzerland, marked by stone pillars. On a clear day, you can also see the Pays de Montbéliard, the Bernese Alps, the Vosges and the Black Forest. At the top of the tower, an orientation table allows you to identify landmarks on the horizon.
