According to local sources, Tulaja Fort was founded five thousand years ago and was then named Til An Ja.[4] The entrance to the fort was located in a cave.[4] Only through the tunnel could the fort be accessed, as it was surrounded by large stones.[4] The area used to receive water from the neighbouring creek.[4]
In October 2021, a team of researchers found that the site is two thousand years old.[5]
It is under the administration of the Tourism Development Corporation of Punjab, a department of the Government of Punjab, Pakistan.[4]
