The earliest architectural relics date back to the Maurya period (c. 300 BCE); in 1966, an inscription of the Mauryan Emperor Ashoka (273–235 BCE) was discovered near Srinivaspuri. Remains of several major cities can be found in Delhi. The first of these were in the southern part of present-day Delhi. King Anang Pal of the Tomara dynasty founded the city of Lal Kot in 1052 CE. Vigraharaj Chauhan conquered Lal Kot in mid 12th and renamed it Qila Rai Pithora.
