Felix Romuliana: Emperor Galerius and a Late Roman Palace in Serbia

In a quiet valley of eastern Serbia, ringed by wooded hills, stand the walls of a palace that a Roman emperor built for his own old age and for his memory. Felix Romuliana, known locally as Gamzigrad, was commissioned by the emperor Galerius in the late 3rd and early 4th centuries and named after his mother, Romula. Its massive towers, its mosaic floors and the two mausolea on the hill above it were designed to be read together, as one landscape of power, ceremony and remembrance. On our small group Balkans tour, the group drives out from its base in Niš to Felix Romuliana on Day 8.

Why Felix Romuliana matters on a Balkans route

It is tempting to treat any Roman ruin as one more stop on a long list. Felix Romuliana rewards a slower reading. UNESCO, which inscribed it on the World Heritage List in 2007 as Gamzigrad-Romuliana, Palace of Galerius, describes it as “a Late Roman palace and memorial complex built in the late 3rd and early 4th centuries, commissioned by the Emperor Galerius Maximianus”. What UNESCO singles out is not any one building but the relationship between them: the spatial and visual links between the fortified palace and the memorial complex, “where the mausoleums of the Emperor and his mother Romula are located”, are in its words “unique”.

That is a useful way to see the place. Felix Romuliana was a home, a stage for imperial ceremony and a site of family memory, set in the countryside rather than in a city. It also belongs to a particular moment, when the Roman Empire was governed by several emperors at once. The route-wide guide to the Balkans History Tour places it among the Roman, Byzantine, Ottoman and Venetian layers that the journey passes through; here, the focus is on what one emperor built, and why.

Galerius: from soldier to emperor of the East

Britannica gives the emperor’s full name as Gaius Galerius Valerius Maximianus. He rose through the army in the years when Diocletian shared power among several rulers, the arrangement historians call the Tetrarchy. Britannica records that Diocletian named Galerius caesar, or junior emperor, on 1 March 293. In 297 Galerius took command against the Sasanian Persians and, after an early defeat, won what Britannica calls a “decisive victory”. ICOMOS, in its 2007 evaluation for UNESCO, links the palace directly to that campaign: the emperor did not begin building “until after his victory over the Persian king Narses in 297”.

When Diocletian abdicated on 1 May 305, Galerius became senior emperor, or augustus, in the East. Britannica describes him as “a staunch pagan” who persuaded Diocletian to begin the persecution of Christians at Nicomedia in 303 and kept it going, and who on 30 April 311 issued “an edict grudgingly granting toleration”. He died the same year. Rome’s earlier emperors, from Augustus to the so-called Five Good Emperors, are covered in our guide to who the Roman emperors were; Galerius belongs to a very different, later empire, shared among soldier-emperors.

UNESCO draws the connection between that military background and the palace itself: “The strong fortifications of the palace are an allusion to the fact that the Tetrarchy Emperors were all senior military leaders.” Felix Romuliana looks like a fortress because its builder wanted it to.

A palace named for Romula

According to ICOMOS, Galerius named the fortress Felix Romuliana after his mother, Romula, whom it describes as Dacian by birth. The name is not a modern label. The Institute of Archaeology in Belgrade records that an inscription reading “Felix Romuliana” was discovered at the site in 1983, in a building with a cruciform ground plan, confirming the identification of the ruins at Gamzigrad.

Sources differ on exactly where Galerius was born. The Serbian nomination, as summarised by ICOMOS, presents the palace as a residence where Galerius could “retire in his birthplace”; ICOMOS itself places it in his place of origin in the province of Dacia Ripensis, today eastern Serbia. The Institute of Archaeology in Belgrade notes that ancient writers recorded Romuliana as the place where he was born and buried. Britannica, by contrast, places his birth near Serdica, the city that is now Sofia in Bulgaria. Either way, the palace was built in the region Galerius regarded as his home, and ICOMOS describes it as the place where he intended to spend the rest of his life.

Walls built like a frontier fortress

The fortifications dominate the site, and they are more complicated than they look. ICOMOS describes a roughly rhomboid enclosure of about 4 hectares, with ramparts and towers surviving up to 15 metres high in places, by ICOMOS’s measure. Excavation revealed two parallel systems of walls. The older, inner circuit had 16 towers, with octagonal towers flanking its gates. The later, outer circuit had 20 towers, built in opus mixtum, the Roman technique of alternating bands of stone and brick. The Institute of Archaeology notes that the older rampart system covers 3.6 hectares, that all 20 towers of the younger system are polygonal, and that its construction is “precisely dated” to 305–306.

Those dates matter. The later walls went up just as Galerius became senior emperor. ICOMOS compares Felix Romuliana with Diocletian’s retirement palace at Split, on the Croatian coast. Both were built by Tetrarchy emperors and both combine fortifications, a palace and temples. But ICOMOS sets out substantial differences: at Split two thoroughfares cross inside the walls, while at Felix Romuliana “a single thoroughfare connects the western and the eastern gates”, and Galerius’s later fortification is the more ornate of the two. “Two monumental gates give access into the fortress,” ICOMOS notes, along with smaller gates and posterns.

Inside the walls: palace, temples and baths

The residential palace stands in the north-western part of the enclosure, with its main entrance on the eastern side. ICOMOS describes an entrance hall whose mosaic floor has “a central representation of a labyrinth”, and behind it a throne room with a raised apse and a mosaic of geometric and hunting motifs. Other rooms include an atrium, where fragments of a fountain survive, and a triclinium, or formal dining room.

Religion had its own place inside the walls. ICOMOS records a small temple of the tetrastyle prostyle type, with four pillars at its entrance, and a sacrificial altar; and in the southern part of the compound a much larger temple, which it says was dedicated to Jupiter and which survives as a podium and staircase. For a ruler whom Britannica calls a staunch pagan, the presence of a monumental temple to the chief god of the Roman state inside his own palace is telling.

The palace also had a bath complex in the classical Roman sequence, with a changing room and cold, warm and hot baths. It was during the excavation of the baths, according to ICOMOS, that a sculpted head in the emperor’s likeness was found. The Institute of Archaeology separately records the discovery in 1993 of part of a larger-than-life porphyry sculpture representing Galerius.

Can you still see the mosaics at Felix Romuliana?

Yes, according to the tour page, which says many of the original floor mosaics can still be seen in situ. ICOMOS reported in 2007 that the mosaic floors left in situ were effectively protected. Some pieces have been lifted, however: the National Tourism Organisation of Serbia says that the most important mosaics from the site are kept at the National Museum in Zaječar. What you see at Gamzigrad is therefore the floors in their original rooms, rather than the complete collection.

Magura hill: mausolea, mounds and an emperor made divine

The palace is only half of Felix Romuliana. About a kilometre east of its main gate, on Magura hill, ICOMOS describes a complex of memorial buildings. Two mausolea stand there, one for Romula and one for Galerius; ICOMOS dates Romula’s to 305 and the emperor’s, which is better preserved, to 311, the year of his death. Beside each stands a consecration tumulus, an earth mound linked to the ritual of apotheosis, by which a dead ruler was raised to the status of a god. ICOMOS describes the tumulus of Galerius as a masonry ring 39 metres in diameter filled with earth in the shape of a cone.

A short distance north-east of the memorial complex, beside the road to the fortress, excavators found the lower parts of four pillars: the remains of a tetrapylon, a four-sided monumental arch. UNESCO explains its significance in the criteria for inscription. The architectural complex of Galerius “intertwines the ceremonial and the memorial programme”, and the relationship between the two parts “is stressed by placing the Tetrapylon on the crossroads between the worldly fortification with the palace and the other-worldly mausoleums and consecration monuments”. Walking from the palace towards the hill, in other words, meant passing from the world of the living emperor to the place where he would be remembered as divine.

This is why Felix Romuliana is best read as a ceremonial landscape rather than a single building. The palace was not a villa that happened to have tombs nearby. UNESCO describes the fortifications, palace and memorial complex as a testimony to Roman building “pervaded by the ideological programme of the Second Tetrarchy and Galerius himself as their builder”.

After Galerius: a Byzantine and Slav settlement

Galerius died in 311, and his palace outlived its purpose. ICOMOS records that it remained in use, but “without royal ceremonies”. Decline set in during the later 4th century, and after Gothic and Hunnic invasions the site became a small Byzantine settlement. It was restored under the emperor Justinian, when a basilica was built; two basilicas, one above the other, date from the 4th and 6th centuries. Raids by Avars and Slavs led to its abandonment at the beginning of the 7th century.

The story did not end there. Slavic communities went on to settle across the former Roman lands of the Balkans, the starting point of our longer account of the history of the Serbs. At Gamzigrad, ICOMOS records that the ruins were revived for the last time as a fortified Slav settlement in the 11th century, while the Institute of Archaeology dates this medieval phase of settlement to the 10th and 11th centuries.

From excavation to World Heritage

Systematic excavation began in 1953. The Institute of Archaeology records that the work started under Professor Đorđe Mano-Zisi, on the initiative of the National Museum in Zaječar and in cooperation with the Archaeological Institute, and that the arrival of Professor Dragoslav Srejović as head of the project in 1970 changed how the site was understood. UNESCO noted at inscription that relatively few excavations had been carried out, and that there were no plans for reconstruction beyond what conservation needs and research can support.

ICOMOS recommended inscription on the basis of criteria (iii) and (iv), and UNESCO inscribed the property in 2007. The protected property covers 179.217 hectares, with a buffer zone of 544.925 hectares, so the inscription takes in the wider landscape around the walls as well as the palace itself.

How much walking does the visit to Felix Romuliana involve?

The tour page does not give a walking distance for the site, but the remains are an open-air archaeological site rather than a museum building. The tour as a whole is rated Level 2, Moderate: participants must be able to carry their own luggage, climb and descend stairs, and take part in 3 to 5 hours of physical activity a day, the equivalent of walking up to 8 kilometres on uneven ground. If you would like to talk through the walking on this day, a Tour Specialist can go over it with you.

What else does Day 8 of the tour include?

Day 8 begins with a guided tour of Niš, taking in its fortress and the Skull Tower. Later the group drives to Felix Romuliana at Gamzigrad, and on the return leg makes a brief stop to see the Roman remains at Medijana. Niš is the group’s base for three nights, from Day 7 to Day 9, and our article on Niš and its Roman, Ottoman and modern history covers the city in more depth.

Felix Romuliana in the story of the Balkans

Felix Romuliana captures a short and particular chapter of Roman history: a few decades when the empire was shared among soldier-emperors, and one of them built a monument to himself in the region he called home. Galerius gave his palace the walls of a fortress, the temples of a pagan ruler, the mosaics of a court and, on the hill above, the mausolea and mounds through which he and his mother were to be remembered as more than mortal. Byzantine villagers, Slav settlers and, in modern times, archaeologists have each added their chapter.

Seen on a journey that also takes in medieval monasteries, Ottoman bridges and Venetian walls, the palace is a reminder of how far back the region’s layers of history go. Travelling in a small group of up to 16 travellers with an Odyssey Program Leader, mature travellers reach it from Niš and can see for themselves the line that Galerius drew between his palace and his memorial.
