Cathédrale Notre Dame de Laon

A little way south of the cathedral is the Municipal Museum (art and archaeology), with a Templar chapel (Romanesque, with a Gothic dome) in the garden. Near the former abbey church of St-Martin (12th-13th C) is the ruined Porte de Soissons (13th C), with a leaning tower.

The interior is notable for its old stained glass, its 18th century choir screen and its valuable treasury. There is a beautiful 13th century cloister, accessible from the chapterhouse. Beyond the choir is the former Bishop's Palace, now the Palais de Justice (Law Courts), with the remains of a Gothic cloister. North of the cathedral is the Maison des Arts et Loisirs, a cultural center with a reading room, theater, exhibition room and conference hall.
