Discalced Trinitarians were brought in to Krotoszyn in 1731 by Józef Potocki, the Voivod of Kiev, the then-owner of the town. 1733 saw erection of a cloister building; in 1766–1772, a brick temple was constructed on the site of a previously demolished wooden church. The edifice’s founder was Ludwika Potocka, nee Mniszech; the church building was probably designed by Karol-Marcin Frantz. The Prussian authorities abolished the cloister in 1819. Today, the building houses, inter alia, an art gallery and a Regional Museum, featuring an interesting exhibition illustrating the history of the town. The temple functions as a parish church.
The baroque single-nave church of Saint Apostles Peter and Paul is an edifice of a diversified solid, with rounded quoins. It is covered by a multi-hipped roof, with an ave-bell on the ridge. Adjacent to the nave at the west is a tower topped with a cupola featuring a lantern. The interior’s uniform late-baroque outfit dates to 1772–1775. A boat-shaped pulpit is an attractive feature.
The former cloister’s standalone storied building is founded on a rectangular projection. Covered by a three-hipped roof, it has in its western elevation an arcade portal dated ca. 1733. The interiors are covered by a.o. cloister vaults with lunettes; a beam ceiling survives in the vestibule.
References:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
