The Oceanside Museum of Art (OMA) is the city's principal visual arts venue, housed in two connected buildings in downtown. It shows contemporary art with a particular focus on Southern California artists and themes — the sea, the desert, the military, and the cultural mix of the US-Mexico borderland all recur in its programme.
The museum rotates its exhibitions regularly and has a permanent collection with regional strengths. Admission is reasonable, and the downtown location makes it easy to combine with a walk to the pier or a meal on the harbourfront. OMA also manages the Top Gun House on Mission Avenue, using it for community events.
