Arch of the Sergii (Croatian: Slavoluk Sergijevaca) is an Ancient Roman triumphal arch located in Pula, Croatia. The arch commemorates three members 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: 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. Read more on Wikipedia
