This is the toilet of the Padishah Emperor, the
Sultan of the Ottoman Empire, the ruler of all the Middle East, northern
Africa, and south-east Europe. This is in the harem, the
private quarters of the sultan, in Topkapi Palace in Istanbul, Turkey.
There's a board over the hole, but you can still appreciate the fine
marble and craftsmanship.
These toilets are representative of mid to late
Ottoman Empire design, and show the Ottoman tendancy to include ornate
design details in the most utilitarian of objects. These toilets are
on exhibit at the Museum of Underwater Archaeology, in Bodrum, Turkey.
