La Collégiale Saint-Thiébaut

Situated in the centre of the old town, the church known as the Collégiale is good example of the style of Gothic architecture that flourished in the Rhine valley in the late Middle Ages. The Cathedrals of Strasbourg and Freiburg in Germany are also built in a similar style.

The building owes its name "La collégiale" to the college of monks who moved to Thann from the nearby town of Saint-Amarin in 1442. Construction of the collégiale took more than 200 years, from the end of the 13th Century through the 15th Century, and was completed in 1516 with the 78m tall spire.

For an extensive study of the Thann collegiate church, circumstances of its erection, issues of patronage, and unique sculptural programs, see Assaf Pinkus, Workshops and Patrons of St. Theobald in Thann (Waxmann Verlag: Muenster, Berlin, New York, 2006).

La Tour des Sorcières (The Witches' Tower)

This was a tower in the old town walls, and built in 1411. The bulbous roof dates from 1628. Today the interior houses a museum dedicated to winemaking.

Le Château de l'Engelbourg (Engelbourg Castle)

The ruins of the Engelbourg Castle sit on a hill to the north of the old town. The castle was constructed in the 13th century by the Counts of Ferrette to control the entrance to the valley and ensure the paying of tolls by those wishing to cross the Vosges by way of the Thur valley and the col de Bussang. The castle was destroyed on the orders of Louis XIV. During demolition, one of towers overturned and cracked into sections, one of which forms a large stone ring known locally today as The Witch's Eye (L'œil de la sorcière).
