This paper presents the results of research on the history of the protection of mills as objects of cultural heritage on Polish lands. First, the spatial distribution of over 20,000 mills at the beginning of the previous century is characterized, then the main actions undertaken for their protection in the nineteenth and twentieth centuries are discussed. Merely 3.4% of mills that worked in the past are now protected as monuments and recorded in the national register. Most of them remain in their original locations (in situ), and another 71 windmills and 22 watermills have been relocated to open-air museums. These specific institutions face a particularly important task involving the necessity to retain the original functionality of the mills.

History of the 17 th century Karczówka monastery church (Kielce) in the light of changes of the roof constructions above the nave and the chancel. A 17th-century church in a monastery complex on the Karczówka Hill in its current borders has been an object of interest of numerous researchers. However, due to insufficient written sources, its building history has not been fully recognized. The aim of this paper is to present the results of architectural research of the roof constructions above the nave and the chancel in connection with the walls and the gables of the church. They have been significantly changed; yet, originally, they constituted three types of trusses: single collar beam truss and king post truss above the chancel, triple collar beam roof and king post truss with a double standing truss above the west arch of the nave, double collar beam roof and king post truss with a double standing truss above the east arch of the nave. Selected elements of the three constructions have been also studied in terms of dendrochronology. The original church (built after

Nowadays, measurement and drawing inventory of architecture monuments is prepared according to very different standards. Thus, in this paper the question about the reasons of such condition will be raised. Subsequently, different measurement methods will be presented, from the manual ones, then tachymetry and photoplan, up till laser scanning technique. There will also be discussed basic purposes at which the documentation should serve. Finally, in the conclusion, the authors will propose three-step standardization of the inventory due to the accuracy degrees, scale and drawing content.
