Immovable heritage consists of buildings, land and other historically-valuable items that are connected by fixed foundations to the ground. In addition to castles, mansions and towers, they include churches, monasteries, rectories, town houses and palaces, rural folk architecture, technical and industrial monuments, theatres, museums, plague columns, wayside shrines and so on.
Of the total number of valuable buildings and premises, almost forty thousand are protected as immovable cultural moments (in addition to over forty thousand movable cultural monuments). The Culture Ministry lists immovable and movable objects or groups of objects as cultural monuments if they provide significant evidence of the historical development, way of life and environment of society from the earliest times to the present, and display the creative abilities and work of people from all manner of fields of human activity, for their revolutionary, historical, artistic, scientific or technical value (or because they have a direct relationship to significant figures or historical events).
Cultural monuments are works of value and their preservation is in the interest of the whole of society. They are thus protected by law by the system of state heritage conservation. For the owner this may mean some limitations, but the result is that it helps to conserve the most valuable aspect of his property.
The National Heritage Institute keeps a register of cultural monuments, the Central List of Cultural Monuments of the Czech Republic (ÚSKP), in which the individual monuments are recorded with list numbers.
The register of cultural monuments is held both in the form of paper records in card files and in digital form in a national online database application, the Heritage Catalogue. Data on immovable cultural monuments are publicly available.
