This study investigates the complex relationship between insectivorous bats and built heritage, focusing on their presence in historic structures such as the 17th-century Chander Nagar Gate in Lucknow, India. While bats play a beneficial ecological role in regulating insect populations and supporting agricultural ecosystems, their habitation within heritage sites raises concerns related to structural deterioration, hygiene, and visitor experience. Employing a multidisciplinary framework that bridges conservation biology, architectural heritage management, and sustainable tourism, this paper evaluates both the ecological importance of bats and their impact on cultural monuments. Field observations, photographic documentation, and pilot deterrent trials using naphthalene were conducted to assess roosting behavior and mitigation outcomes. Results revealed minor guano-related staining but no immediate structural erosion, with species such as Pipistrellus pipistrellus showing adaptability to artificial lighting. The study further explores non-invasive management strategies, including acoustic deterrent devices, light modulation, and installation of bat boxes, emphasizing the importance of tailoring interventions to specific site conditions and species behavior. In parallel, the paper addresses visitor attitudes and potential conflicts through proposed survey instruments, advocating for inclusive tourism strategies that balance biodiversity conservation with public comfort and safety. It concludes that bats need not be expelled but rather managed through evidence-based, site-sensitive approaches that uphold both ecological and heritage values. This integrated model supports the dual goals of conserving biological diversity and sustaining the cultural integrity of heritage tourism destinations.
