Brother Klaus Field Chapel

The Chapel is a private donation of the farmers Josef and Trudel Scheidtweiler in Mechernich-Wachendorf. It was planned and constructed by the Swiss architect Peter Zumthor in 2007 and is dedicated to the Swiss mystic Nicholas of Flüe, also called Bruder Klaus. The structure of the monumental, monolithic chapel is made from tamped concrete. Inside one can still see the imprint of trunks which were used as centring and burned down later. A drop-shaped skylight was also left from the trunks, which is not sealed and allows rain, snow or sunlight inside.

St. Mariä Heimsuchung is located in Impekoven, a district of the municipality of Alfter in Nordrhein-Westfalen.

Bonn Cathedral was built in the 11th century as the Romanesque collegiate church of St. Cassius and Florentius of Cassius Monastery. In 1583-1589 and 1689 the cathedral was considerably destroyed. The building was restored between 1883 and 1889, in 1934 and after the Second World War.
