It is not known whether the caves were natural or excavated.
After the Nirnaeth Arnoediad, the Sindarin Elf Annael led his people into Androth, where in hardship they hid successfully for several years. Annael fostered the First Age hero Tuor in these caves to the age of sixteen. Annael eventually left the caves, planning to relocate to the Havens of Sirion, but his group was attacked and defeated by the Easterlings, who took Tuor as a slave. Tuor later escaped back to Androth and lived there alone for four years before leaving to meet his destiny at Dor-lomin.
