Catching on to the New York trend of highline walkways, in 2015 Milan opened up access to a series of rooftop walkways traversing the grand steel-and-glass structure of the Galleria Vittorio Emanuele II shopping arcade. The roof-line views of the arcade's cruciform shape and Liberty mosaics is stunning, as are the views of the Duomo, Teatro alla Scala and the Torre Velasca.
