Quri Qale Cave is a cave located northwest of Ravansar, Iran, and is one of the longest caves in western Asia. First explored in the 1950s, in 1989 it was further opened by an Iranian team. It contains three main chambers, with calcite crystals, stalactites and waterfalls. It is known for its colony of mouse ear bats, and for a number of archaeological finds, including silver plates dating the late Sassanian period.
