Statue of Poseidon, Bronze sculpture at Götaplatsen, Gothenburg, Sweden

The Statue of Poseidon is a bronze sculpture by Carl Milles on Götaplatsen, standing seven metres tall in contrapposto on a shell-shaped elevation within a fountain basin 120 cm high. Poseidon holds a water-spurting fish in his right hand and a shell in his left, wearing a stylised mussel on his head. The basin holds six smaller sculptures and reliefs of tritons, naiads, fish and mermaids.

For the 1923 Gothenburg Exhibition, Carl Milles designed a temporary plaster fountain on the site, funded with 80,000 kronor by the Charles Felix Lindberg donation fund. The present fountain was inaugurated on 20 November 1927, and the Poseidon figure was unveiled on 24 September 1931 before 20,000 spectators. The fountain basin was cast in Stockholm and the central groups in Copenhagen.

The statue was originally to be named Neptunus, the Roman sea god, before Poseidon was chosen. It has often been dressed up: Chalmers students have put a white lab coat on it, and it has appeared as the Hulk, Scrooge McDuck and in a red flamenco skirt by artist Josefine Chiacchiero. A smaller version stands at Millesgården on Lidingö.

The statue stands at the southern end of Avenyn on Götaplatsen, reachable on foot or by tram along the boulevard. The square is paved and open, so the sculpture can be viewed at any time of day; the fountain's water system runs in the warmer months.

The most retold myth about the fountain claims that Gothenburg's burgher women found the original version too bold, so Carl Milles reduced Poseidon's genitals and positioned the fish in his hand so that it resembles a large phallus when seen from the Concert Hall steps. The sculpture is nicknamed "Milles' revenge".
