Bantony Castle is a historic structure located in Shimla, Himachal Pradesh. Built in 1880 during the British era, it served as the summer palace for the Maharaja of Sirmaur. The castle, which showcases an impressive blend of Gothic and Victorian architectural styles, is now part of Shimla's heritage zone and included in the Shimla Heritage Walk for tourists.

Originally, the estate featured both Bantony Castle and Bantony Cottage. The two-story castle, with its sloping roofs, mini-towers, and traditional wooden architecture, is a testament to the grandeur of the colonial period. Though some parts of the castle are still being refurbished, it remains a popular spot for history enthusiasts and tourists eager to explore its storied past.
