My friend and I stumbled across the Bell Tower while we are walking around Xi'an City at night. Located near the Drum Tower, it looks magnificent with the bright lights emitting from it and certainly stand out from the other malls and buildings surrounding it. We didn't enter it though.

It is not worthwhile to pay for entrance fee, but u can take photo from the opposite road. The sightseeing at night will be more beautiful, as lighting will around the building! U can walk from the bell building from there, just 5-10 mins.
