Qasr Libya
Qasr Libya or Theodoureas is a small town in northern Libya about northwest of Bayda. In ancient times, it was called Olbia and Theodorias, the ruins of which were excavated in the 1950s. The town contains a museum with fifty Byzantine mosaics. It's on the cross-roads between the eastwards Marj–Bayda main road, and the southwards Qasr Libya–Marawa road.
