Tirumamani Mandapam is the mandapam in front of bangaru vakili and is constructed in the year 1417 AD by madhavadasar. From the Tirumamani Mandapam, one can enter the Bangaru vakili (translates to Golden Entrance) to reach the inner sanctum sanctorum. There are two tall copper images of the dwarapalakas Jaya and Vijaya on either side of the door. The thick wooden door is covered with gilt plates depicting the dasavataram of Sri Maha Vishnu. The doorway is directly in line with the Padi Kavali and the Vendi Vakili(Meaning Silver Corridor in Telugu). It admits pilgrims to the Snapana Mandapam. Suprabhatam is sung in front of this door.
