The location of the subject of November’s photo is in Valencia, Spain.

In what was once part of the Turia riverbed, the city fathers built a park. Starting in 1996, the park became the site of The City of Arts and Sciences, a complex of buildings dedicated to the pursuit of entertainment and culture.
