The Gothic church in honour of the Assumption of the Virgin Mary is the main cathedral of the city. The construction of this three-nave basilica began in the middle of the 14th century, when the church was destroyed during the Mongol-Tatar raid of 1241. It was finished in 1397, when the architect Mikolaj Werner erected the vault of the middle nave. It took another century, however, to put up the two towers, to add the chapels and to cover the vaults. The northern tower is crowned by a tall Gothic spire rising from a gilded crown. from a gilded crown, the southern tower a low Renaissance helmet.
The polychrome interior of the church, with an abundance of superb paintings, sculpture and stained glass windows, presents a wide panorama of styles, from Gothic and Baroque to Art Nouveau. But the focus here is always on the temple's greatest treasure of the temple - the huge main altar by Vít Stvoš (second half of the 15th century). Carved from lime, this polyptych has become a recognised a late Gothic masterpiece with Renaissance elements.
