Stiftskirche St. Cyriakus in Quedlinburg

You're standing at the collegiate church of Saint Cyriakus in Gernrode, one of the most important Ottonian churches in Germany. Start with the west end. That's the westwork, flanked by two round towers. They were added in the twelfth century, but the heart of the church is much older. Building began in 959, more than a thousand years ago.
