We start our walk at the Church of St. John of Jerusalem Behind the Wall, probably the oldest brick temple in Poland.

Next to the church is a very old district called Śródka. The origin of the name comes from the day when the markets were organized (Środa means Wednesday). Before the "new city" was established on the opposite side of the River Warta, Śródka had been granted some sort of municipal charter. One of the traces of the old urban structure in Śródka is the medieval square with the Church of St. Margaret.
In 1253 the dukes of Poznań, Przemysł I and his brother Bolesław, ordered all Śródka residents to resettle to the newly-established city.
