It has a large vault-shaped room with smooth walls and features a protected entrance and stone corridor for added security. Inside, there is a rectangular stone formation of unknown purpose. Towards the end of the room, a small stone wall leads to a narrow and dark section, which opens up to a natural entrance featuring a beautiful fig tree.
