text: Architecture In spite of the extensive destruction Haguenau suffered during the many wars experienced by Alsace, especially the Thirty Years' War, the French conquest in 1677 and the Second World War, it still possesses monuments from nine centuries, even if nothing is left of arguably the most prestigious of them, Frederick I Barbarossa's imperial palace (Kaiserpfalz).
  Medieval Haguenau retains three gates from its former fortification, the Tour des Chevaliers (Tower of the knights), the Tour des Pêcheurs (Tower of the fishermen) and the Porte de Wissembourg (Wissembourg gate), two fairly large Gothic churches, Saint-Georges and Saint-Nicolas, an ancient water-mill and the old custom-house (Ancienne Douane). Both Saint-Georges and Saint-Nicolas Church have lost many of their artistic treasures over the centuries, especially their medieval stained glass windows and outside sculptures. Still, both display to this day some fine liturgical furniture (altars, choir stalls, organ cases, church tabernacles, calvaries...). Saint-Nicolas has become the receptacle for the baroque wooden decoration of the church of the destroyed Neubourg Abbey nearby.
  French Baroque and classicism has bequeathed the town several buildings, among which the former hospital and the current town hall. The Synagogue (1820) is a fine example of French Neo-classicism, as is the theatre (Théâtre municipal) (1846). The large Hop hall (Halle au houblon) is a good example of historicism in architecture. It was built by the French in 1867 and extended twice by the Germans, in 1881 and 1908.
