Bergama, Turkey

This museum has several interesting artifacts from ancient Pergamum that help bring the ruins to life. There is even a faithful replica of the Zeus Altar.

This huge brick edifice was built in the 2nd century as a Roman temple to the god Serapis and later converted into a Byzantine church.

Pergamum's 2nd-century Asklepion was a famed temple and medical center dedicated to Asklepius, the god of healing. Some treatments used a sacred water source that was later discovered to have radioactive properties.
