Thiruvenkadu, located near Sirkazhi in Tamil Nadu, is one of the most revered Navagraha temple towns, famous for the Swetharanyeswarar Temple dedicated to Lord Shiva and Lord Budhan (Mercury). Known as the Budhan Sthalam, this temple is believed to remove Mercury-related doshas and bless devotees with intelligence, wisdom, communication skills, and success in education and arts. Legends say Lord Shiva performed his fierce Rudra Tandavam here, giving the temple immense spiritual power.
Beyond the Budhan Temple, Thiruvenkadu is surrounded by many ancient shrines that enhance its spiritual importance. Devotees often combine their pilgrimage with nearby Navagraha temples such as Vaitheeshwaran Koil (Mars Temple) and Keezhaperumpallam (Ketu Temple). Visiting Thiruvenkadu is not only an astrological remedy but also a profound journey into wisdom, health, and divine blessings.
