- There are a number of urban legends that claim that buildings which show a less-decorated facade to a now-more-important direction were accidentally constructed back to front. For example, the Kelvingrove Museum in Glasgow, Scotland, which was constructed to face the university campus, meaning that the main entrance from the street is actually the back of the building.
- A related urban legend tells how some buildings (especially on college campuses) were supposedly built "backwards", with the more elaborate architecture and ornamentation on the less-used side, or where you couldn't admire it from a distance.
