Grossmunster

This Romanesque-style Protestant church is one of four major churches in Zurich. Inaugurated in 1220, Grossmunster was reportedly ordered by Charlemagne in the 9^th century when he discovered the graves of the city's patron saints Felix and Regula there. The church has enormous bronze doors from 1523 with images depicting the Reformation and Sigmar Polke’s stained glass windows, made out of agate, which were installed in 2009.
