Citizen groups and heritage advocates in Bengaluru have voiced strong opposition to the proposed tunnelling work near Lalbagh, warning that it could violate heritage protections and impact the city's fragile water table
During a meeting with the Geological Survey of India, citizens stressed that Lalbagh's geological formations, particularly the ancient Peninsular Gneiss, are irreplaceable and must be preserved.
Participants argued that the site's integrity is non-negotiable and called for the proposed North-South tunnel road project to be rerouted away from the garden.
Officials stated that an expert committee is currently examining the feasibility and potential impact of the project. However, residents expressed scepticism about claims that tunnelling at a depth of 60 metres would be safe.
They emphasised that Lalbagh is not just a local landmark but a shared natural heritage, protected under existing laws, including provisions dating back to a 1975 notification and the Ancient Monuments framework.
Several attendees also raised alarms about Bengaluru's shrinking green cover and declining groundwater levels. They warned that any disturbance to Lalbagh's ecosystem could have long-term consequences.
Describing Lalbagh as the 'lungs of the city,' citizens urged authorities to prioritise environmental sustainability over infrastructure expansion.
The discussion also touched upon efforts to secure UNESCO World Heritage status for the Peninsular Gneiss formations. GSI officials noted that while geo-heritage data has been submitted, Lalbagh has not yet been selected due to criteria that often favour non-urban sites.
An expert team, comprising specialists from multiple cities, has already conducted a site inspection and is awaiting further project details to complete its assessment.
Officials clarified that the Geological Survey of India will submit its findings to the Union and state governments, which will take the final decision on the proposed tunnel project.
Meanwhile, citizen groups continue to advocate for the protection of Lalbagh, urging authorities to consider alternative routes that do not compromise the city's natural and cultural heritage.oject, citing risks to heritage, geology, and groundwater levels.
