List of Classified Structures
The List of Classified Structures was a National Park Service database of buildings, roads, monuments, artifacts, and other objects at/near United States National Parks. The database classified the structures by location, type, historical contribution, etc.; and identifies each by structure, LCS, and database record numbers, e.g., Acadia National Park BLDG0001 is a historic district contributing structure with "LCS ID" 006582 and RECORDNO=30.
In 2020, the database was merged into the Cultural Resources Inventory System. It replaces three legacy inventory systems: ASMIS, CLI, and LCS, and reinstates the ERI. The Historic Structures section will be called CRIS-HS.
