Sri Santhana Srinivasa Perumal Temple is located at Mogappair, literally means blessed with a child, in Chennai. This name symbolizes the belief that the Lord of Sri Santhana Srinivasa Perumal shrine provides the childless couples the most wanted blessing of little babies. Due to this belief childless couples throng to this holy place and offer their prayers, and it is said that their wishes have come true after the visit of this shrine. The Santhana Srinivasa Perumal Temple has been conducting many major religious festivals, one to note is Brahmotsavam. With the Brahmotsavam in full swing, the popular abode of Perumal wears a celebrity look with people thronging its boundaries, waiting to get a glimpse of the Lord and His Consort, decorated with precious jewels and full of colorful flowers, as they move out in the surroundings on a variety of vahanams to bless devotees.
Mogappair was once Maga-p-peru (meaning "blessed with a son"). This name derived from the belief that the deity in the Santhana Srinivasa Perumal Koil there granted the blessing of parenthood to childless couples. After persistent mispronunciation, the name `evolved' to its present form.
This 650 years old temple is very powerful to give the boon of a child (santhanam) which is called Maha-Peru in Tamil and that's how the place became Mugappair. The main deity Santhana Srinivasar is 9.5 feet high. Couples praying for child take the Santhana Srinivasar vigraham in their lap as part of their prayer. Thulaparam is also being done. Poojas are taking place throughout the day till the Ekantha Seva in the night as in Thirumala.
