Why does Caen's Church of Saint-Jean lean?

The church we know today is old, but it is not the oldest building to have stood in this spot, or at least, this area. It is believed that a place of worship dedicated to John the Apostle (or Jean in French) has stood in this part of Caen since the early 7th century. The former building was likely only a smaller chapel of which no real trace remains; the current church began construction in the 14th century, nearly seven hundred years later.

A troubled history of conflict

Much like the city it stands in, the Church of Saint-Jean has been no stranger to conflict throughout its lifetime. In 1417, during the Hundred Years' War, the English laid siege to Caen, the church was damaged in the fighting. During the French Revolution, the church was reportedly closed and converted into a saltpetre plant for several years, which damaged the structure's interior; the building was only returned to its function of worship in 1802.

It was around a hundred years after this that the church was classed as an historic monument, prompting repairs by the French government. During the Second World War, it became one of the city's rare buildings to survive the Allied bombings of Caen during the Battle of Normandy.

The church post-war

Marc Brillaud de Laujardière was the architect tasked with the reconstruction of Caen after the war; he also dealt with fortifying the foundations of the Church of Saint Jean. By 1969, the church was also fitted with new stained-glass windows.

The church today, with its modern stained-glass windows, but also its mix of flamboyant Gothic architecture and Renaissance features, is a true smorgasbord of styles, giving it a unique character and design. Another quirk of the Church of Saint-Jean is the fact that its lantern tower was never fully constructed; it remains only partially finished today.

So, why does the church lean?

Conflict, varied architecture, damage sustained over centuries, none of this explains why Saint-Jean leans. The explanation is actually rather simple: much like Pisa, the Church of Saint-Jean was built on marshy ground. In fact, the whole neighbourhood around the church used to be an island, one which has long since been covered up by streets and pavement.

That is also likely the reason why the lantern tower was never completed; the architect in charge of the project likely realised that the church was too heavy for the ground it was set on and called off its construction.

So despite, or rather, thanks to its slightly odd appearance, the Church of Saint-Jean is now one of Caen's curiosities. A survivor, through centuries of conflict and peace, it stands proudly, though slightly ajar, in the city centre. A charming reminder that imperfections are often what give the world character.
