The Decanal Church of St. Bartholomew is both the dominant of Kolín as well as the most valuable monument of this historic town. The early Gothic church was founded in the middle of the 13th century and its construction was carried out in several stages by orders of King Přemysl Otakar II and his successors, the last construction works were done at the beginning of 14th century.

The whole area of the so-called Cathedral Hill, which was revitalized extensively in 2018–2020, is truly unique. You will find here most notably the ossuary with rich ornamental decoration or the building of the former parish school, which houses an interactive exposition. The bell tower is a place where the cathedral treasure is kept and a lapidarium can be found. From atop it also offers a view of the town centre. The green baileys invite you to have a walk and relax in the herb garden or in the rosarium.

The Museum of Folk Architecture in Kouřim is the only open-air museum not focused on a single region in the Czech Republic, which collects construction monuments from the territory of Central, Eastern and Northern Bohemia, thus offering a direct comparison of various regional types of folk architecture from the 17th to the 19th century. There are fourteen larger residential and farm buildings, which are complemented by several smaller monuments.

The Roman Catholic cemetery church of All Saints with an ossuary is part of the former Cistercian abbey in Sedlec, founded as early as 1142.
