This picture is the other major location of Sardis. Here, there is a main road (which the people are standing on), a bunch of workshops, a public restroom, a public bath house, a gymnasium, a synagogue, a playing field and more. The large structure in the back of the picture is the gymnasium. The white columns just behind the people are a part of the synagogue. It is interesting that the synagogue is located amid everything else. (If anyone is interested in pictures of the synagogue, I can post some, just let me know.) The location of the synagogue might suggest that Sardis was quite a syncretistic place and that the Jewish people had not secluded themselves from the rest of society.
Here is a picture of the gymnasium. As you can see, it has been preserved well. The decorations and engravings and colors are elaborate and beautiful. If you look at the frescos, you can see Greek engravings. Of course, Greek did not have punctuation or spaces, as is attested to in these markings.
This is a photo of me standing next to a capital (the top of the column). You can see how massive these things were. Basically, to make the columns, workers would build them in layers. They would stack layer upon layer until the column was at the specified height. They would use large ramps and ladders (akin to scaffolding today) to get the pieces on top of one another. Sardis is mentioned in Rev. 1.11 and 3.1ff.
This is a picture of a public restroom. You can see the seats on the wall (notice how close to one another they are!) and just below a kind of flume or tunnel. This flume had running water in it so that when the people relieved themselves, the waste would drop into the flume and be carried off.
Here is a restroom sign located just outside of Sardis. I thought it was quite humorous. If you ever go to Turkey, make sure to get a stack of coins (lyra) for your trip because you have to pay to use the public restrooms (no matter where you go). This particular restroom costed 75 cents I believe.
