The Shark House is a suburban Oxford oddity: a terraced house in Headington with a large fibreglass shark appearing to crash nose-first through the roof. It is not a museum or a long stop, but it is one of the city's more memorable pieces of public-facing eccentricity.
The detour makes sense if you are already in Headington or enjoy architectural jokes and local controversies. Be considerate: it is a private house on a residential street, so the visit should be brief and quiet.
