The International Monument to the Reformation, usually known as the Reformation Wall, was inaugurated in 1909 in Geneva, Switzerland. Key individuals, events, and documents of the Protestant Reformation are depicted therein in statues and bas-reliefs.
The Wall is in the grounds of the University of Geneva, which was founded by John Calvin, and was built to commemorate the 400th anniversary of Calvin's birth and the 350th anniversary of the university's establishment. It is built into the old city walls, and the monument's location there is designed to represent the integral importance of the fortifications, and therefore of the city of Geneva, to the Reformation.
