Kumhrar or Kumrahar is the area of Patna where remains of the ancient city of Pataliputra were excavated by the Archaeological Survey of India starting from 1913.

Since no other stone works were recovered, it is thought that the pillars sustained a wooden roof, and that there were no surrounding walls, making it an open-air hall.

South of the pillared hall, seven wooden platforms were excavated, which are thought to have supported a staircase going into the canal to welcome guests.

[8] Spooner initially thought that the pillars that were not found had sunk into the ground, but later research by Indian archaeologist Altekar showed that instead they had been removed by locals and reused for construction purposes.
