The Allianz Arena was designed for FC Bayern München and TSV 1860 München. A cascade of colour - white, red and blue - can be projected onto the smooth lozenge-shaped curved exterior made of inflatable ETFE cushioned panels, depending on which team is playing at home. Roller blinds installed under the roof may be drawn during games to provide protection from the elements. The panels can be lit from the inside and are self-cleaning. The project was completed in 2005.
