Gol ghar 156 stairs highest point in Bihar,Patna

Me,Sataybrat and Aditya was on the Gol ghar having 156 stairs.
It was wonderful to see the rest of the Bihar on highest point.
Satyabrat was last among us to ascend on Golghar hahaha...
i came to know that this place is used to store the taxes from the peoples in olden era.
