View looking northwest at the (entrance) to the Library at Nysa. The west (left) and east (right) walls of the building are well-preserved. This structure was built around AD 130. It was at least two, and possibly three-stories high. This is the best-preserved library in Anatolia—the famous "library" at Ephesus is a reconstruction!
It was a multi-functional building that served as a library, auditorium and courthouse. There were shelves for the scrolls/codices and a platform for judges and tribunals. Stairways led up to the second and third stories. During the sixth-century, it went out of use as a library and eventually served for workshops, living quarters, and burials.
