This is absolutely greatest place I have seen so far. We can not compare this place with any monuments in AD era. I saw the pottery in purana Quila museum claimed to be 5000 years old but these paintings are unparalleled as claim to be 30K to 5K years old. Declared world heritage by UNESCO in 2003.
About 1000 years old group of Hindu temples known as Baijnath Dham temple in Uttarakhand. It is small but when you are on Uttarakhand visit you must visit this. This carries our rich history and eternal faith. Inspite the Katyuri kingdoms (800 to 1100 AD) were on flee due to frequent invasions from Chand dynasty of Kannauj, later Nepalis, the Katuri kingdom gave a lot of treasure to Uttarakhand in form of temples and hence founded the eternal faith and we are continuing the same rich tradition today.
