St. John’s Church (Kościół św. Jana) in Słońsk

The current Catholic parish church in Sonnenburg (Słonsk) was built as a church of St. John and consecrated in 1508. Since 1550 the knighthood of the Knights of St. John took place in this church. The building, a late Gothic three-aisled hall church with a magnificent star vault, was therefore richly furnished. The interior of the church is characterized by the late Gothic tendril painting of the vault in yellow and green tones with flowers in the middle of the surfaces. The painting was rediscovered and renewed in 1925 under several whitewashes. In the central nave, the tendrils are interrupted by the coats of arms of all 24 master masters since 1305, beginning with the eight-pointed St. John's Cross. The coat of arms of the city of Sonnenburg ends above the organ choir. More than 200 gold-plated keystones in the network of the vault show saints, martyrs, Madonnas, guild signs or images of animals.

The church received its current form after a town fire in the early 19th century. The church tower hood, which was still baroque at the time, fell into the roof. Under the leadership of Karl Friedrich Schinkel, the roof and tower were rebuilt between 1814 and 1817 in the style typical of the time. The window frames were also given a new design.
