GAMZIGRAD, ROMULIJANA (near Zajecar) Arriving in Zajecar again on the way to eastern Serbia, you can visit the archeological site of the ancient Roman imperial palace - Felix Romuliana, which was never completed for Emperor Gaius Valerius Maximianus Gallery, and which Justinian restored and used as a border fortress in the 6th century.
