The Swiss Inventory of Cultural Property of National and Regional Significance (German: Schweizerisches Inventar der Kulturgüter von nationaler und regionaler Bedeutung; French: Inventaire suisse des biens culturels d'importance nationale et régionale; Italian: Inventario dei beni culturali svizzeri d'importanza nazionale e regionale) is a register of cultural property in Switzerland.
The register contains both mobile and immobile items of cultural property including old towns, quarters, squares, villages, sacral buildings, houses, castles, bridges, monuments, archaeological sites and collections.
The selection is based on the significance of the items in the domains of history, aesthetics, art, typology, ethnography, social studies and in other scientific disciplines, as well as on their rarity value.
Items of purely local significance are not included; these may be registered separately by the cantonal authorities.
[1] The Federal Office of Civil Protection has made the 2009 register of A-class objects (current as of 1 April 2010) available on the Internet as a geographic information system and as a set of PDF documents.
