Lahariya Shib Mandir, also called Lahariya Baba Dham, is the Shiva temple of Lahariya village in Baghmundi block, at the foot of the Ajodhya hills beside the small Lahariya reservoir and below the Lower Dam. Quiet for most of the year, it fills with thousands for its Gajan and Charak fair before Chaitra Sankranti in mid-April, a festival known locally for bringing Hindus and Muslims together.
The temple stands where the road from the plains begins its climb to the Lower Dam, and travellers bound for the hills often stop here first. In front of it lies the reservoir known as Lahariya Dam, and behind it rises the great embankment of the PPSP's Lower Dam.
It is a working village shrine rather than a monument, and its deity is known as Lahariya Baba. Bengali Wikipedia's list of Ajodhya sights calls it an old Shiva temple; no reliable date for its founding has been found. Its priest in 2025, Tapan Mahato, said his forefathers had run the temple's fair before him.
