The Seljuk Turks supported traffic on the Silk Road by building a series of caravan serai, fortified stopping points for the caravans moving east and west along the silk road. These inns were one day's travel apart. That has turned out to be about 10 kilometers. The typical inn provided space for animals, a mosque, food, a marketplace and shelter. Most importantly, their high walls were sealed at sundown, providing essential protection from bandits.

The Sultan Han Caravanserai is in a great state of reconstruction. This is part of the interior.

We reached our first Roman ruin, Side, very late in the day. Nevertheless, the theater was in relatively good shape. The hippodrome at Side is the best preserved in Turkey, but not very photogenic.

Another late-day photograph. But here we can see how close Side is to the Mediterranean. Obviously, this was a trading town, with excellent sea connections to other parts of the Roman Empire. The arches in the distance were the Side baths. Every Roman town had its baths.

Perge is another ancient city near the Mediterranean coast. It was quite a sophisticated city, with this secondary gate protecting the central part of the city.

Down the center of the principal shopping street, Perge had a stream of flowing water, fed by a spring above the town. This water flowed over a series of weirs, each forming a small waterfall. Very elegant.
