The stone carvings of the dwarapalakas Jaya & Vijaya, the historical remains at Sree Narasimha Parthasarathi temple, are believed to have an ancientness of thousand and more years.     Tipu Sultan's invasion and the East India Company's rule caused critical changes in the life of the feudal lords and their dependents.  When the native rulers and their entourage turned into paupers and weaklings, they were compelled to accept the realities of the time.    Along with numerous other temples, Thiruvangoor Sree Narasimha Parthasarathy Temple also remained in a state of neglect for years, without any daily pujas or rituals.  The temple was covered with shrubs and weeds till the middle of 20th century.   The renovation efforts of the temple were initiated by Mangalagiri Swamikal, a sage from the nearby matt (monastery) on the other side of the road.   In 1954 under his leadership the local residents joined together to revitalize the temple and the surrounding area.  Through their efforts the sanctum sanctorum and outer pavilion of the temple were renovated and rebuilt.    The re-consecration ceremony took place in 1974 with the installation of new idols, restoring sacredness and revive the spiritual energy of deities and temple. 

After the re-consecration, the temple's growth gained fast momentum and with the help of the local people, the temple managing committee constructed various facilities in the temple.  Balikallu Puras (Holy Rock Shrines), Chuttu Mathil (outer wall), Agrasala (feasting hall), Theerthakulam (temple pond), Chuttu Vilakku (outer lamp), Devavahanams (divine vehicles),  Rathapura (chariot shed), Devi Temple, Annakshethram (dining hall), office building, quarters for the tantris (priests) and circumambulation path around the temple are few of them.   In 2003, Ashtabandha Navikarana Kalasham, Dhwaja Prathishta (flag installation), and Sahasra Kalasham (a sacred ritual involving a thousand kalashas) were performed to amplify the spiritual energy of the temple manifold, thereby bestow prosperity and well-being upon the community and to elevate this sacred site to the status of a Mahakshetra (a great temple).
