Visit of the church of Ottmarsheim – Jewel of the Romanesque art

What if one of Alsace's most beautiful Romanesque churches was hidden away from the main tourist routes? I'm taking you to visit Ottmarsheim Church, east of Mulhouse, right on the Rhine. Its Saints-Pierre-et-Paul Abbey and its unique octagonal layout in Alsace truly surprised me: it's a Romanesque art gem, and it's free to discover!

Ottmarsheim Abbey: A Unique Octagonal Layout in Alsace
A Romanesque Church from 1049 on the Alsace Romanesque Route
Located on the Alsace Romanesque Route, the Saint-Pierre-et-Saint-Paul Church of Ottmarsheim was built between 1030 and 1040 by Rodolphe d’Altenbourg, one of the founders of the Habsburg family, before being consecrated in 1049 by the Alsatian Pope Leo IX.
Frescoes and Four-Level Elevation: What to See
This 11th-century church has plenty to surprise you:
- 🏛️ A central octagonal layout, a copy of the Palatine Chapel in Aachen, Germany, making the abbey unique in Alsace
- 🪜 A four-level elevation to admire from the inside
- 🎨 Frescoes inside the church
You’ll truly marvel as you step through the church door: it’s pretty from the outside, of course, but I didn’t expect so many wonders upon entering! It’s worth spending a little time there to observe all the small details.


Guided and Theatrical Tours of the Abbey
Even if the church of Ottmarsheim can be visited freely, I advise you to take a guided tour in order to learn more about the history of the place but also to discover all the sumptuous details of the exterior and the interior of the church.
For individuals, guided tours are not regular: you need to contact Ottmarsheim town hall to book, so it’s best to inquire before coming.
Classic guided tours are organized regularly, but also theatrical tours. Having had the chance to attend one of them, I can only recommend it. You will learn a lot about Ottmarsheim in the company of Rodolphe or Cunégonde, Count and Countess of Altenbourg. It’s both fun and very informative!
