Also known as St Leopold's Church, this Art Nouveau masterpiece by Otto Wagner defines Vienna’s architectural cityscape and is recognised as the first example of a Modernist church in Europe. Distinctive components of Art Nouveau style were the ornaments that are especially exposed on the dome of the church and on the altar.

The Gartenbaukino with its impressively large screen is one of the last remaining single auditorium cinemas in Vienna. The cinema is the central performance venue of the Viennale, the successful international film festival held in Vienna every year. Night screenings, premieres and many other spectacular events are also held here.

Built between 527 and 565 AD at the foot of Mount Sinai for Emperor Justinian, this monastery later took its name from St Catherine of Alexandria, whose remains are said to rest here. It’s more fortress than church, with thick stone walls guarding the Church of the Transfiguration, the chapel of the Burning Bush, and a monks-only library packed with ancient manuscripts. Inside, you’ll find mosaics, religious ornaments, and some of the oldest illuminated manuscripts in the world on display. Outside, don’t miss Moses’ Well and the garden with centuries of history. The place is open most mornings but closed on Fridays, Sundays, and Orthodox feast days. Still active today, the monastery holds importance across Christianity, Judaism, and Islam, and continues its Greek Orthodox traditions uninterrupted.
