Arrondissement of Thann

The Collégiale Saint-Thiébaut (Saint-Theobald collegiate church) in Thann, Haut-Rhin is one of the most ornate Gothic churches in the whole Upper Rhenish region (Alsace, Baden, North-Western Switzerland, Palatinate). Of its 76 meters high spire, it is said that "The spire of Strasbourg is the highest, the spire of Freiburg is the broadest but the spire of Thann is the prettiest." In spite of its name, the church is actually dedicated to Saint-Ubald, of which it keeps a finger as a relic. It is listed as a Monument historique since 1841 by the French Ministry of Culture.
