As a tribute to the city's Reformation founders John Calvin, John Knox, Guillaume Farel and Théodore de Bèze this impressive monument stands over 30 feet tall and over 300 feet long. Made of quartz and granite, the Monument de La Réformation sits on the ramparts at the promenade des Bastions. The statue is simplistic but its size is what attracts visitors. The monument features statues of additional Reformation leaders such as Martin Luther, Ulrich Zwingli and Oliver Cromwell.
