Pracheen Mandir Chandrakoop, means ancient, mandir, koop if you translate it word by word. It's a 5000-year old temple with a well inside. The well is also known as Draupadi Koop, legend has it that Draupadi used to take a bath in that well every day. Remember the game of dice that was one of the strongest reasons behind the war of Mahabharata? Pandavas had lost everything to Kauravas in the gambling game. They had put their material wealth, themselves and their wife Draupadi at stake. Hence, Draupadi was asked to come to the court by Duryodhan. When she refused, angry Dushasana grabbed her by hair and dragged her forcefully to the court where he tried to unwrap her sari in front of all Kauravas and Pandavas. Owing to this humiliation, Draupadi vowed not to tie her hair till she washes them with Dushasana's blood. It was at this koop where she washed her hair with his blood after Bhima killed him in the war.

The temple is dedicated to Shree Shyam Ji, who was the grandson of Bhima. His original name is Barbeek. He donated his head to Lord Krishna and got a boon in return that his head will stay alive to witness the war, and people will worship him as Shyam in Kalyuga. Mahabharata's Vijay Stambh (Victory Column) is located next to the Koop where his head was placed after the war, some water from the well was sprinkled over his face, and he was asked who made Pandavas win the war? Hence, this temple is constructed in the honour of Barbeek, who is now known as Shree Shyam Ji.
