The district town of Usti nad Labem, was founded at the confluence of the Labe (Elbe) and Bilina Rivers. The valley in which the city is situated is sheltered by two steep cliffs - Marianska on the north and Strekov on the southeast - and two hills. Of the historical monuments in Usti, special attention should be paid to the Church of Ascension of the Virgin Mary. This medieval town church is probably of early Feudal origin, even though it was only mentioned for the first time in 1249. The Baroque Church of St. Vojtech has been reconstructed several times and today serves as an exhibition and concert hall. Tourists should also visit the nearby Strekov Castle, which was built by John of Luxemburg about 1319 in order to protect river navigation. Likewise, it is also possible to visit the nearby castle of Krasne Brezno, which was built circa 1603.
