Bikaji ki Tekri

Bikaji Ki Tekri, the city's original fort, is one of the top Bikaner tourist attractions. This is the oldest building in Bikaner, having been built by Rao Bika roughly 500 years ago. The construction is fascinating, with red sandstone or Dulmera stone forming a significant portion of the fort. If you go down to the basement, you'll find yourself in a room-by-room puzzle.
