Former Abbey Königsfelden

Königsfelden Abbey (Kloster Königsfelden) in Windisch, canton Aargau, is one of Switzerland's key medieval monastic sites. The Habsburgs founded it on the spot where King Albrecht I was killed in 1308, and today it is best known for the Gothic stained glass inside its church.

Why is there an abbey in Windisch?

King Albrecht I was murdered on 1 May 1308 near Windisch by his nephew, Duke John. His widow, Queen Elisabeth, endowed a monastery here so that prayers would be said for the dead ruler. The Habsburgs called it Königsfelden, "the King's Field".

The complex combined two communities: a convent of Poor Clares and an attached house of Franciscan friars. The friars moved in during 1311 and the nuns followed a year later. Albrecht's daughter Agnes, widow of Hungarian king Andrew III, settled in the convent in 1317 and made it prosperous through land purchases and careful management. After her death in 1364 the abbey slowly declined.

What can you see?

• The abbey church – a plain Gothic mendicant-order church with a long choir.
• 14th-century windows – made around 1325–1330, they rank among the finest medieval glass-painting cycles in Switzerland, alongside the choir glazing of Bern Minster. The church served as a Habsburg memorial.
• The monastic buildings – after the Reformation Bernese governors resided here, and since 1868 a psychiatric clinic has occupied part of the site, so not every area is open to visitors.
• Roman Vindonissa nearby – Windisch sits on a Roman legionary camp, with remains and an amphitheatre that pair well with an abbey visit.

When to go and how to visit

The church is open to visitors from April to October, normally 10:00 to 17:00 and closed on Mondays. Museum Aargau has managed it since 2009. Check klosterkoenigsfelden.ch for current hours and ticket prices. Visit in daylight to see the windows at their best.

How do you get there?

Windisch lies right next to Brugg on the railway line, a short train ride from Baden and about half an hour from Zurich. From the station you can walk or take a local bus. Combine the trip with nearby Habsburg Castle, the dynasty's ancestral seat.

They form a cycle from the first half of the 14th century, regarded as the most important in Switzerland together with the glass of Bern Minster. The Habsburgs commissioned them.
