An ancient cellar and tunnel were discovered at the Gajendra Moksha Kalyani (pond) of the Sri Ranganathaswamy temple here, which has a history of more than 300 years.

The ancient remains came to light during the desilting of the pond, as per the instructions of District In-Charge Secretary Amar Narayan. During the works, a Banni tree present in the pond since the past 30 years, was uprooted and planted elsewhere.

The desilting has been taken up in view of the famous Rathasapthami festival to be held on Feb. 17, during which the temple elephant Gajendra takes a holy dip in the sacred waters of the pond. As the desilting work commenced on Tuesday, two smaller tunnels going in opposite directions within the main larger tunnel were discovered.

The Archaeology & Museums Dept. has been notified about these finds which may have immense historic significance.
