The Arch of the Sergii, also called the Golden Gate, stands at the south end of Pula's old town and was built to commemorate three members of the Sergii family who served under Augustus at the Battle of Actium in 31 BC. It is a single-span triumphal arch decorated with Corinthian columns and elaborate floral ornament — a compact but beautifully detailed piece of late Republican Roman architecture.
The arch once formed part of the city wall; it now stands at the edge of the old centre, near the Sergi Street (Ulica Sergijevaca) which passes under it into the Forum quarter. James Joyce lived briefly in Pula in 1904–5 when he taught English at the Berlitz school here, and the arch appears in his letters from this period — he found Pula dull, but was taken with the Roman ruins.
