Sannur Cave is a visually dynamic[1] karst-based subterranean environment, made from groundwater traveling inside the Eocene-era limestone of Galala Plateau, Egypt.
[2] The Sunnur area is dated at approximately 65-million years,[3] and is considered an important geological heritage.
Sannur Cave system was discovered in the 1980s, roughly 71 miles (115 km) south-southeast of Cairo, after quarry blasting created an overall entrance.
It is a limestone cave overlaid with alabaster created by thermal springs.
Its unique geology and unusual formations of stalactites and stalagmites led it to being recognized as an Egyptian Protectorate in 1992.
