There are remains of many Buddhist stupas and monasteries, which are about 1500–2000 years old, and there is also a group of Hindu temples from the 9th century. Based on the multiple archaeological excavations undertaken here, archaeologists have sent the proposal to Archaeological Survey of India (ASI) to include this site in the list of protected heritage site. Several popular annual festivals are held here, including the five day long National Saraswati Festival in January, Adi Badri Akha Teej Mela in Vaisakh around April–May, week-long Adi Badri-Kapal Mochan Kartik Purnima religious mela around November.
