The National Cadastre of Locally Protected Buildings is part of the Lechner Knowledge Center's "3D-based Data Infrastructure" project, funded by the European Union. The cadastre contains most of the locally protected man-made buildings. The interactive map application covers the entire area of Hungary and it can be used to locate these protected objects based on settlement, address, and parcel number. The map helps the users to get to know the values of their local environment, such as a residential buildings, sculptures and street furnitures.
