aiola island bridge

The Murinsel in Graz, Austria, is an artificial floating "island" in the middle of the river Mur and links the two banks on both sides. At night the blue navigation lights that surround the structure light up. This landmark of Graz was designed by New York City artist Vito Acconci on the occasion of Graz becoming the 2003 European Capital of Culture.
