Nagunuru or Nagaruru is a small inconspicuous village near Karimnagar. Naganuru was the seat of power for many dynasties and had been an important centre of political and religious activities for nearly four centuries under the Chalukyas of Vemulavada, Western Chalukyas of Kalyani and Kakatiyas of Warangal. The inscriptions which are available in the village and by structures which can be seen even now, there seems to be a huge mud fort in this place
An inscription dated A.D.946, written during the reign of Arikesari II of Vemulavada and which is present on four sides of a stone pillar mentions the name of the village as Nagaruru (this inscription is still kept in the Museum of Karimnagar)
The inscriptions, statues etc which are available plenty indicate that this place has been a popular centre for Jainism as well.
Most of the temples in this region have been constructed in 12th and 13th centuries and the passage of the time and the negligence of the local's took its toll. Some of the temples which still exist though in a dilapidated stage and which make us understand the earlier grandeur of the place. Some of the temples are Trikuta Temple, Siva temple, The Vaishnava temple, Ramalingala gudi.
