About Addala Mandapam (Mirror Mandapam)
Twelve feet to the north of ‘Sri Krishnadevarayala Mandapam’, there is a glass porch. Every day at 2:00 PM a service called Dolotsavam or Unjal Seva is performed to the Srivaru in this glass porch. Devotees are permitted to participate in this paid seva.
In reality, this seva is a north Indian contribution. There is no evidence to prove when this was built. There is enough evidence to prove that this Seva Programme began to be performed in 1831.
