The Tanjai mamani kovil was moved frome a place called Vambulal Salai to a its present location at Vennatrankarai during the rule of Maratha king Tulsa between 1763-1787. The same king is said to have moved the Singa Prumal kovil (Narasimhar Swamy kovil) from Melveli thottam to its present location near Tanjai mamani kovil. The Mani kundram temple was previously located in Kalimedu and latter moved to a location near Vennatrankarai in between Neelamega Perumal kovil and Melsinga Perumal kovil, and is also known as Nadu kovil.
