(CNN) -- [Updated 3:30 p.m. ET, Monday, May 9] This photo was taken in Valencia, Spain, last month during Semana Santa (Holy Week) celebrations.
Holy Week, which starts on Palm Sunday and ends with Easter, is observed by Christians worldwide. But it's hard to imagine festivities as colorful as those in Valencia's maritime district.
There, a slow, extravagant procession takes place every year on Good Friday. The procession recounts the story of Christ's death through 28 separate "brotherhoods." Each brotherhood -- made up of local parishioners -- has a unique costume and theme as it symbolizes a specific aspect of the Passion.
Credit goes to "rodolfosiles" for being the first commenter to correctly point out that the photo was taken Spain during Semana Santa. And "wolfpack654" was the first to mention Valencia specifically. Well done.
