This is the only remaining tunnel that leads to the Sultan´s mosque from my previous post.
During the mid-18th century, the Sultan of Yogyakarta (Java, Indonesia), began work on the Taman Sari complex. Comprised of lavish gardens and pools, it also featured a bizarre man-made sea, connected beneath the ground with underwater tunnels and small island buildings.
One of these island structures was used as a mosque, and was only accessible by underwater passage.
