It’s almost a shame that a building as gorgeous as the Pavilion 21 Mini Opera Space is only temporary. This mobile aluminum structure was built by the Austrian architecture firm COOP HIMMELB(L)AU for the Munich Opera Festival 2010.

According to Dezeen, the Pavilion 21 Mini Opera Space, which features a multifunctional stage and seats three hundred, is made up of shimmering pyramids that increase its surface area and reflect external sounds. It is meant only for the Opera Festival, but there is no word as to where exactly this prismatic structure will go once the festival is over (is there a place where beautiful temporary architecture goes to die?).
