Church of Saint John of Jerusalem outside the walls

The Church of Saint John of Jerusalem outside the walls is a Roman Catholic parish church in the city of Poznań in western Poland. The original church on this site was built at the end of the 11th century, making it one of the oldest churches within the present boundaries of Poznań.

It stands on the south-eastern corner of the Rondo Śródka roundabout, between the neighbourhoods of Śródka and Komandoria, within the city's Nowe Miasto district. It is close to the north-west corner of Lake Malta. The epithet "Outside the Walls" refers to the fact that it lay outside Poznań's medieval defensive walls.
