Salona

Part of the Salona ruins.

In the early 7th century the Roman limes on river Danube and Sava fell and was militarily abandoned, leaving Roman province of Dalmatia open for conquest. The events of the fall of the city because to its location are relevant to the understanding when the province and coastal cities periphery succumbed to barbaric invasion.[22] Pope Gregory I in July 600 wrote to the archbishop of Salona, Maximus, in which he expresses concern about the arrival of the Slavs ("de Sclavorum gente quae vobis valde imminet et affligor vehementer et conturbor").[23][24] According to De Administrando Imperio (10th century) and Thomas the Archdeacon's Historia Salonitana (13th century), Salona was largely destroyed in the seventh century invasions of the Avars and Slavs (more specifically the Croats per Thomas the Archdeacon who also identified them with Goths and Slavs[22]). In the DAI's chapters 29 and 30 on the history of Dalmatia and fall of Salona, the terms Avars and Slavs were interchangeably used but, most probably, generally meant the Slavs.[25] The city was reportedly conquered by trickery when the Avar-Slavs, previously defeating at the river Danube or Sava (possibly also near Cetina[25][22]) a Roman army dispatched from Salona/Klis, in disguise passed the frontier castrum of Klis and expelled the Romans from the city. When it became their possession, they "settled and thereafter began gradually to make plundering raids and destroyed the Romani who dwelt in the plains and on the higher ground and took possession of their lands".[20] Refugees from Salona settled in other coastal and island cities (Decatera, Ragusa, Spalato, Tetrangourin, Diadora, Arbe, Vekla and Opara) and inside Diocletian's Palace.[20][26]

The exact date of destruction and fall is uncertain. Pope John IV sent abbot Martin (possibly future Pope Martin I[27]) to Dalmatia in 641 to redeem captives, which was interpreted that Salona must have been destroyed before that date.[28] As Salona's refugees are also said by Thomas the Archdeacon to have founded Ragusa around 625 it meant that Salona had to be destroyed around 625 or before.[28] In the scholarship, it was traditionally dated to 614,[28][26] although opinions varied between 608 and 639.[28] The last dated inscription, reflecting existence of life in the city, in the ruins is dated to 12 May 612.[28][26] However, 1970s were found many coins, out of which few were of Heraclius and youngest minted in 630/631. It is interpreted as evidence that the city was rather becoming steadily abandoned after 614 and probably destroyed in 639.[28] Some other archaeological excavations probably show a small group of people continued to live with newcomers until mid-7th century when it became abandoned.[28] Tibor Živković argued that the attack happened in the early 630s and became abandoned after that time.[29]

The new Slavic population settled outside the ruins to the East near river Jadro, where are found Old-Croat graves. In the 10th and 11th centuries, Croatian kings founded and rebuilt three churches, of which of St. Stephen was used as a royal mausoleum of Croatian Kings (with found sarcophagus of Croatian Queen Helen of Zadar), while of St. Peter and Moses (so-called Hollow Church) was crowned king Demetrius Zvonimir.[30] The archaeologically confirmed information is found in Historia Salonitana.[31]

Remnants of the Basilica and cemetery outside of the town.

These are the remnants of the Basilica and cemetery outside of the town. The earliest parts of the complex date back to the second century BC. The bishop and martyr Domnio was buried here after being executed in the arena of the amphitheater on 304AD.[2]

At the end of the fourth century, the complex was partly destroyed during the German incursions, and in the mid-fifth century, a three-nave basilica was constructed on top of the ruins. Many sarcophagi can be found here. in the early seventh century, the cemetery was looted and partly destroyed.[2]

The cemetery exhibits a feature of Christian cemeteries at that time to have deceased buried as close as possible to the martyr or Ad sanctos.[2]

Tusculum

Architectural and ornamental fragments, capitals inscriptions, and columns from the area were replaced in a building built in 1898. It was restored in 2008.[2]

City wall

The construction of the Salonitan city walls took several centuries. The earliest part of the city was surrounded by walls as early as the second century BC. During the Pax Romana the city expanded to both east and west.[2]

During the reign of Emperor Marcus Aurelius around 170 A.D., under the constant threat of Germanic tribes, the east and west suburbs were included in the walls, which were fortified with at least 90 towers. Some parts of existing buildings were used in the extensions to the walls, thus making them integral. The total circumference of the elliptical shape of the walls was approximately 4 km (2.5 mi), with varying width from 1.9 to 2.5 meters (6.2 to 8.2 ft).[2]

During the reign of Emperor Theodosius II in the early fifth century, all the towers were reconstructed, as witnessed by an inscription on the walls.[2] Furthermore, in the first half of the sixth century, triangular-shaped endings were added to some square-shaped towers to improve the city's security and defense system. Such examples are visible today on the northern side of the Urbs orientalis.[2]

The center of Christian Salona is in the northwest part of the eastern city. Here is an Episcopal center with twin lengthways basilicas, a baptistery, and Bishop's Palace were built in the fifth century A.D.[2]

This Basilica is the largest in the entire area of Dalmatia. The best-preserved part of the oldest part of the city (Urbs vetus) is the eastern wall and Porta Caesarea with two octagonal towers and three passages; one for cart traffic and two for pedestrians on each side of the wider passage. The central passage was probably equipped with a movable grid, as indicated by grooves on side pylons.[2]

Aqueduct of Salona

Emperor Augustus built an aqueduct to supply the city with water from the river Jadro. It was 3,850 meters (12,630 ft) in length, and the best-preserved part is north of the episcopal center. Calculations show that the aqueduct could supply enough water for about 40,000 people.[2]

Thermae

The thermae were typical buildings of Roman civilization and an indispensable part of Roman urban life. Although the city of Salona had multiple baths, the best-preserved and largest ones are those in the eastern part of the city called the Great Thermae, built in the second or beginning of the third century A.D. This building is rectangular, with three symmetrically arranged apses in the north and one in the west. There was an adjoining elongated spacious room to the north, housing a semicircular pool, the piscina, filled with cold water, the frigidarium. There were two dressing rooms to the left, with benches for sitting and openings in the wall for clothes. The room to the west was also used as a massage room, the unctorium.[2] The room ending with an apse served both as a lounge and an exercise room. To the right there were hot baths and sauna: caldarium, tepidarium and sudatorium.[2]

Five Arches Bridge

In the eastern suburb of Salona, five arches spanned the westernmost backwater of the river Jadro. The bridge carried one extension of Decumanus Maximus which branched into two roads, one of which led north-east to the Porta Andetria gate, while the other one led across the bridge to Epetium, today's city of Stobreč.[2]

The Porta Caesarea is a well-preserved gate with two octagonal towers and three passages, one for cart traffic and two for pedestrians on each side of the wider passage. The central passage was probably equipped with a movable grid, as indicated by grooves on side pylons. Porta Caesarea was constructed using large regular stones primarily for fortification purposes. After eastern and western expansion had occurred, the gate lost its primary purpose and became carrying construction of the aqueduct. According to Kähler's reconstruction, the gate had two floors, of which the top one was very elaborately decorated with half columns, composite capitals, and window openings. Within the gate, there was a small courtyard for defense purposes.[2]

Southeast of the ports Caesarea, a luxurious villa has been uncovered, which was probably the palace of the Roman governor of Dalmatia. Several mosaics depicting mythological figures such as Apollo Orpheus and Triton I've been transferred to the archaeological museum in Split.[2]

The center of the town's public life was in the southeast part of the old town. It is 45 m × 70 m [ 148 ft × 230 ft ] in size. After the fourth century A.D., as the town became more Christian, the forum started to lose its role as the city center.[2]

A theater 65 m × 58 m [ 213 ft × 190 ft ] in size was built in the first century A.D.[2]

South of the theater, there is a temple that was dedicated to either Dionysus or Liber.[2]

These ruins are the remnants of the oldest cemetery basilica. It was built in the middle of the fourth century above the graves of four Praetorian guards who were executed in the arena during Diocletian's persecution of Christians.[2]

Amphitheater in Salona

At the westernmost point of Salona, in the second half of the second century A.D., under the influence of Flavian architectural style, a monumental building was erected. The presence of a Roman amphitheater indicates that gladiator fights were held in the city of Salona until the fifth century, when they were finally banned. The building was ellipsoidal in shape, with three floors on the south side and one floor on the north side, conveniently laid down on a natural hillside. Despite its relatively small size (125 by 100 meters (410 by 328 ft) outer shell and 65 by 40 meters (213 by 131 ft) the arena), the Salonitan amphitheater could have been occupied by 15,000 up to 18,000 spectators. The auditorium was divided into three tiers, the lower two with seats and the upper one for standing. In Diocletian's time, the top tier was covered with a porch. Through poles attached to the outer shell of the building, the whole arena could be covered with canvas, giving protection from the sun and rain. There was a state box for the Province governor on the south side and opposite it seats of honor for the city magistrates. In the center of the arena, an opening led into an underground corridor whose purpose was the disposal of dead gladiators' bodies. On the south side of the amphitheater, beneath the auditorium, there were two vaulted rooms where gladiators worshipped Nemesis, the goddess of revenge and destiny. During Diocletian's persecutions of Christians, the amphitheater was used as a site of executions.[2]

Only parts of substructures of this monumental building, as well as some fragments of architectural decoration and stone sculpture, have been preserved. The amphitheater was most severely damaged during the wars against the Turks in the 17th century when Venetians had it demolished for strategic reasons.[2]

This cemetery complex has the martyr Anastasios thrown into the bay with the grindstone around his neck in 304 AD. The mausoleum was built in the early fourth century. In the fifth and sixth centuries, other bishops and priests were buried here.[2]

Gradina means a medieval hill fort built on the east walls by the Turks after capturing Klis.[2]

Roman Sarcophagus at Salona

Burying the dead inside the city was against Roman law, so Romans buried their dead on the roads leading out of the city.[2]
