A 10th century fort at Nizamabad , Quilla Ramalayam was built by the
Rashtrakutas. It was formerly known as Indoor or Indrapuri. In 1311, Quilla Ramalayam was occupied by Allauddin Khilji and later it was captured by the Bahamanis, the
Qutub Shahis and the
Asaf Jahis.
The existing fort has a large area surrounded by masonry walls along with huge bastions at the corners. It resembles the Asaf Jahi style of architecture with spacious halls and a summerhouse. A 40 ft monolithic victory pillar here is a major attraction. Another important feature at Quilla Ramalayam is the Bada Rammandir Temple, built by
Samarth Ramdas, the guru of
Chhatrapati Shivaji. The fort offers a beautiful view of Nizamabad town and its surroundings.
