The Puerto Rico Register of Historic Sites and Zones (Spanish: Registro Nacional de Sitios y Zonas Históricas) is a Puerto Rican government program adopted by the state Planning Board (Junta de Planificación) for use by both private and public entities to evaluate, register, revitalize, develop or protect the built historic and cultural heritage of Puerto Rico in the context and for economic planning and land use zoning.[1][2]
There is an overlap between the Register of Historic Sites and Zones and the federal National Register of Historic Places (Registro Nacional de Lugares Históricos), however, properties can be listed in the former and not in the latter and vice versa. Properties inscribed in the register can be either individual sites or historic districts (zonas históricas) consisting of multiple structures, buildings, and sites. As of 2024, there are more than 260 sites and historic districts listed in the Puerto Rico Register of Historic Sites and Zones.[2] Sites can be listed in the register through legal codification by either the Puerto Rico Planning Board, the Puerto Rico State Historic Preservation Office or the Financial Advisory Authority and Fiscal Agency of Puerto Rico through a Real Property Evaluation and Disposition Committee which has been in place since 2023.[3]
