The cavern contains Derbyshire's largest stalactite and there are unique 'poached egg' stalagmites. The inscription encircles the minaret below the stalactite cornice. Benxi offers a boat ride through a large stalactite filled cave and underground river. This creates a hollow stalactite, or icicle, referred to as a brinicle. Another type of stalactite is formed in lava tubes while lava is still active inside. It is famous for the stalactite that is worshipped as the lingam. Above the panel there is a marble stalactite cornice. The minaret is divided into several stories by stone molding and stalactite galleries. The interior is lined by two crossed arches with a central stalactite dome. The buildings make frequent use of muqarnas (stalactite vaulting). This type of formation results in an irregularly-shaped stalactite, looking somewhat like stretched taffy.
