Saint John Chapel

The chapel was built in 1269 within a large enclosure intended for the Order of the Knights Hospitaller of Saint John of Jerusalem.

Enlarged from 1351, it underwent a further extension around 1500 with the addition of a side chapel by Marc Oeler, commander of the order.

Twenty years later, he also commissioned murals depicting scenes from the life of Saint John the Baptist, patron of the commandery, as well as the Passion of Christ.

These works, of great stylistic quality, remain mostly unfinished, with some scenes only sketched with partial application of color.

The arrival of the Reformation in Mulhouse in 1523, which led to the departure of the Knights of Saint John, may explain this state.

After the sale of the order's assets in 1798, the chapel was successively used as a brewery and then a blacksmith's workshop.

Purchased by the city in 1892, it was restored and from 1898 housed a lapidary museum, with some remains still visible in the garden and inside the building.
