Sri Kalyana Venkateswara Swamy Temple stands at Srinivasa Mangapuram, west of Tirupati, and is one of the more meaningful satellite temples in the Tirumala pilgrimage orbit. The shrine is associated with Venkateswara and Padmavathi after their marriage, which gives it particular importance for newly married couples and pilgrims who cannot manage the climb or crowds at Tirumala.
The temple is administered by Tirumala Tirupati Devasthanams, so rituals and queues follow the organised pattern familiar from the wider Tirupati circuit. It is a practical half-day addition if you are visiting Chandragiri or the Srivari Mettu footpath. Dress conservatively and expect temple security rather than casual sightseeing.
