The palace at Felix Romuliana, located in eastern Serbia near the village of Gamzigrad, was built by the Tetrarchic Roman emperor Galerius beginning in the late third century CE. According to the Epitome de Caesaribus (40.16), emperor Galerius was born and buried in Dacia Ripensis at a place
that he had renamed Romulianum in honor of his mother.
In 1984, at a
fortified site in eastern Serbia long suspected as a place of imperial import, the discovery of an inscription confirmed the
site’s identification as the place attested as the birth and burial spot of
emperor Galerius. The palace was named a UNESCO world heritage site in 2007.
Puzzlingly, the palace is surrounded by two circuits of fortification walls built in extremely close chronological succession and both maintained in the palace's eventual manifestation. Other features at the site include a Palace Complex of formal reception rooms decorated with high quality mosaics, two temples, a small bath complex, a horreum, and two monumental burial complexes associated with the imperial family located approximately 1 kilometer away atop Magura Hill. Beginning in the 4th century, the site served a Christian population, as evidenced by the construction of two successive basilica churches.
