The construction of the St. Catherine’s basilica in Braniewo began in 1346. It was erected in the same place where there was already a wooden church from around 1280. In 1381, the construction of the choir and the church corpus was completed. It was used fully from 1399, although many years have passed until the completion of the work. Around 1426, work was undertaken on the construction of a huge tower, at the foot of which two chapels were created. In 1500, bishop Luke Watzenrode founded on the eastern side of the north aisle, a brick matroneum, closed with a stellar vault. In the 17th century, the church received extensive equipment, including the main altar, wooden priestly stalls and benches for city councilors. The temple has suffered many damage over the years. In 1480, as a result of a lightning strike, in 1520 during the Prussian War and the worst during the Second World War, when only the south side, the half of the north side and the eastern choir, were preserved. One stump remained from the tower, but 9 of the 10 massive pillars of the central nave survived. The restoration and restoration took place in 1979.
