The mighty ramparts and towers of the imperial palace Felix Romuliana are evidence of the immense power wielded by its founder, Roman emperor Galerius Maximianus.The emperor, born in the area of the present-day city of Zaječar, chose to build the monumental palace near his birthplace to honour his mother Romula, after whom the edifice was named Felix Romuliana.
Inside the walls, which once protected the city from barbarian incursions, you will find the remains of the palace divided into two distinct parts. In the southern part there are remains of a large temple with two crypts and an ancient Roman bath. This section also includes the remains of the infrastructure facilities needed to run and maintain the palace - including a typical Roman warehouse (horreum), which was used to store grains and wine, as well as a single-nave building with a porch.
And in the northern part of the site, you will find the exceptionally well-preserved imperial palace complex with a small temple and an altar, where ancient pagan rituals once took place.
The floor mosaics attract the attention of visitors with their multicoloured figurative shapes and geometric patterns. The most important mosaics from the site are kept at the National Museum in Zaječar.
Felix Romuliana is a rare late Roman archaeological site from the Tetrarchic period and the best-preserved example of Roman court architecture of the period. Its immense cultural and archaeological importance has been recognised by UNESCO, which declared it a World Heritage Site in 2007.
