Arch of the Sergii is an Ancient Roman triumphal arch located in Pula, Croatia. The arch commemorates three brothers of the Sergii family, specifically Lucius Sergius Lepidus, a tribune serving in the twenty-ninth legion that participated in the Battle of Actium and disbanded in 27 BC . This suggests an approximate date of construction to 29-27 BC. The arch stood behind the original naval gate of the early Roman colony. The Sergii were a powerful family of officials in the colony and retained their power for centuries.
The honorary triumphal arch, originally a city gate, was erected as a symbol of the victory at Actium. As the main inscription proclaims, it was paid for by the wife of Lepidus, Salvia Postuma Sergia, sister of the three brothers. Both of their names are carved in the stone along with Lucius Sergius and Gaius Sergius, the honoree's father and uncle respectively. In its original form, statues of the two elders flanked Lepidus on both sides on the top of the arch. On either side of the inscription, a frieze depicts cupids, garlands and bucrania.
This small arch with pairs of crenelated Corinthian columns and winged victories in the spandrels, was built on the facade of a gate (Porta Aurea) in the walls, so the part, visible from the town-side, was decorated. The decoration is late hellenistic, with major Asia Minor influences. The low relief on the frieze represents a scene with a war chariot drawn by horses.
This arch has attracted the attention of many artists, like Michelangelo.
References:Carlsten is a stone fortress built on the orders of King Carl X of Sweden following the Treaty of Roskilde, 1658 to protect the newly acquired province of Bohuslän from hostile attacks. The site of Marstrand was chosen because of its location and its access to an ice free port. Initially a square stone tower was constructed, but by 1680 it was reconstructed and replaced by a round shaped tower. Successive additions to the fortress were carried out, by the inmates sentenced to hard labour, until 1860 when it was reported finished. The fortress was decommissioned as a permanent defense installation in 1882, but remained in military use until the early 1990s.
The fortress was attacked and sieged twice falling into enemy hands. In 1677 it was conquered by Ulrik Frederick Gyldenløve, the Danish military commander in Norway and in 1719 by the Norwegian Vice-Admiral Tordenskjold. At both occasions the fortress was returned to Swedish control through negotiations and treaties.
