The first Romanesque church was founded by the knightly families of the Gryfit and the Ostoja before 1257, i.e., before the town was founded. In 1618, thanks to the efforts of Mikołaj Zebrzydowski, the Discalced Carmelite nuns were settled there, and between 1619 and 1621, a monastery designed by Giovanni Battista Trevano was erected for them. The Early Baroque church, also designed by Trevano, was built between 1637 and 1640, on the site of a Romanesque church. The construction was funded by the dowry of her sister Teresa Maria, daughter of Prince of the Rhine Ferdinand Falzgraf. During the Swedish Deluge, the church was turned into a Protestant congregation and was returned to the Order in 1686. It was moved to the new Monastery and Church of Saint Teresa at Wesola Street in 1787 and was later put up for sale. In 1816, the church was handed over to the Protestant congregation as compensation for the threefold destruction of the Protestant church at Świętego Jana Street. To this day, the building remains as it was in the 17th century, with only its decoration changing. 
It is a modest, ricked, single-nave rectangular-plan church with an undistinguished rectangular presbytery. The two-storey façade is crowned by a triangular gable with vases, and decorated with Tuscan pilasters, niches, and a window in a richly ornamented frame. White walls and barrel vaults with lunettes, stucco decoration, and pilasters with Ionic capitals dominate the interior. It is an ecumenical church, which is why the classicist main altar from 1870 features a painting of Christ calming a sea storm, a work by Henryk Siemiradzki from 1882, and above it a wooden Gothic crucifix from 1370 and a stained-glass window from the inter-war period designed by Adam Ciompa. In front of the altar is the baptismal font and above it is the pulpit. At the entrance, attention is drawn to the bas-relief epitaph of Mikołaj Rej, a work by Jan Raszka from 1921, destroyed by the Germans during World War II. 
The church hosts concerts of religious music, mainly organ and chamber music. In the 1950s, a string quartet played here, and a children's choir, later a mixed choir, now a vocal ensemble, sang here. The Polish Bach Society, which promotes the works of Johann Sebastian Bach and other musicians, has been active since 2003. The church resounds with mainly organ music, and hosts music festivals, evangelical choir performances, charity concerts and recording sessions.
