The "Big Cathedral" of Zürich is a 12th century Romanesque ex-cathedral with a fascinating history of Catholic saints and Protestant preaching. According to legend, the Grossmünster was founded by Charlemagne after his horse stopped over the graves of three early Christian martyrs.

Four francs and 200 narrow, uneven stone/wood steps take you to the top of the highest of the towers. Its spires and tops were actually destroyed after a fire in 1763 and then were reconstructed with the Gothic-style sections that can be seen today.

The four balconies of the tower provide marvelous views of the city, including several other nearby churches such as the Fraumünster or the Peterskirche. In addition, it is fascinating to see the Limmat river flowing out of the lake of Zürich from high above.
