Burg Kreuzenstein on a hillside near Vienna, Austria, there has been a castle here since the middle ages. However, the current "castle" is a collection of castle rooms and towers collected in the late 19th century from all over Europe.. It houses large collections of furniture and furnishings. Visiting Kreuzenstein is like getting a quick dip into architecture, wealth, and art throughout medieval Europe.

Gasometer City in Vienna The "Gasometers" are four towers, built 1896-99 for storing the city's coal gas. When the city converted to natural gas in 1984, the containers were no longer used and converted to residences, community centers and shopping. Now some 2000 people live in them, and the "Gasometer city" has become its own community. Located in the industrial 11th district known more for its public housing from the early 20th century (bottom of the picture), the Gasometer city and the metro line have brought new life to the area. The greenery behind the towers is the wooded part of the Prater park, reachable on foot or bicycle directly from the towers.
