Investigate the protection status of a historical monument
Trace the LMI heritage code through cadastral maps, orthophotos and archival records to document conservation buffer zones.

Locate the asset in the Historic Monuments List, recording its LMI code, heritage tier (A or B), chronology and official address.

A pitfall to avoid
Street addresses in the Historic Monuments List can be obsolete or renumbered by municipalities. Relying solely on addresses without cadastral and cartographic cross-referencing leads to misidentifying protected plots.
