The protection and administration of Kerala's monuments fall under a dual governmental structure. Sites of national importance (like Bekal Fort and St. Angelo Fort) are maintained by the Archaeological Survey of India (ASI), a federal agency under the Ministry of Culture, specifically managed by the Thrissur Circle.
Sites of state and regional importance are governed by the Kerala State Archaeology Department. Local municipal corporations, such as the Kochi Municipal Corporation and the Thiruvananthapuram Corporation, play a significant role in maintaining the urban infrastructure, sanitation, and zoning laws in the "heritage zones" surrounding these monuments to prevent unauthorized construction and preserve the aesthetic integrity of the areas.
