Bolzano's four-storey contemporary art space is housed in a huge multifaceted glass cube, a brave architectural surprise that beautifully vignettes the old-town rooftops and surrounding mountains from within. There's an impressive permanent collection of Italian and international artwork; temporary shows are a testament to the local art scene's vibrancy, or often highlight an ongoing dialogue with artists and institutions from around the world. The river-facing cafe has a terrace perfect for a post-viewing spritz.
