Presiding over Rynek Śródecki, this charming landmark has a history that dates back prior to 1231. Its surviving Gothic elements date back to the first of many rebuilds in the late-15th century. Destroyed by Swedes during the Thirty Years War (1618-1648), the church was again rebuilt in 1658. Originally a Śródka parish church, a curate’s fascination with St. Phillip Neri lead to the 17th-century addition of a chapel in his honour; Śródka became home to the country’s first Philippine Order congregation soon afterwards, and St. Margaret's came under the purview of the Philippine friars across the street until 1805. During World War II the church operated as a repository for books that Poles were trying to spare from destruction; surviving relatively intact, it was partially renovated and repainted in the late 1940s. Today it is a rectorial church in an archdiocese parish.

Surrounded by a low wall, the main entrance curiously features a tower with no steeple, revealing the Gothic stair gable behind it. Amidst the largely Baroque interiors, don't miss the gorgeous flower-adorned vaulted ceilings, and keep an eye out for two paintings of note by an unknown local artist from the early 1600s: the Holy Mother with Child on a Crescent Moon - painted on a wooden plank on the northern wall of the presbytery; and Madonna with Child Surrounded by Angels in the Chapel of the Sacred Heart of Jesus.
