• The Romanesque Church: dates from the middle of the XIIth century but the construction started in the Xth century.
• The Protestant Church: built on the site of the Barn of the Protestant Massacre (1562), it now houses a museum where an exhibition and a slide show with sound about the Wars of Religion and the presence of the Protestant community in Wassy are displayed.
• The old town: the Place Marie-Stuart (Mary Stuart Square) was built on the site of the former stronghold with architecture typical of the 19th century; the Tour du Dôme (Dome Tower), the gates and the ramparts; the cast iron art work in the park.
• The Town Hall: the astronomical clock, paintings (Pernot, M. Calvès, Humblot), the socio-cultural centre and the hospital chapel: the vault and the paintings of Joseph Constant Menissier.
