In the last decade, hypogene speleologenetic processes have attracted attention of speleological community. Many previously epigenic caves have been reinterpreted as hypogene. Some basic publications on the topic have triggered doubts and debates because similar cave patterns and wall rock features considered as hypogene can be formed also under other conditions. Therefore, the aim of the 21th IKS is to present basic hydrogeological and chemical principles and processes of hypogene speleogenesis as well as geological conditions leading to it.   Special attention will be paid to the geometry of cave passages and wall rock features   which are often interpreted as hypogene, but could have as well formed otherwise, such as in
meteoric flood-water conditions or by dissolution in contact with sediment.
