One of the most recognizable buildings in the world, the Burj Khalifa rises to a staggering height of 829.8 meters (2,722 feet). The towering edifice appears to pierce the sky itself, a glimmering vision of contemporary design that soars high above the rest of the city. Completed in 2010, the skyscraper broke records to become the world's tallest freestanding structure, beating landmark buildings such as the Petronas Towers and CN Tower. Its outdoor Observation Deck is set on the 124th floor and offers breathtaking views of the city, surpassed only by the Sky Deck on the 148th floor. The extravagant interiors only add to the building's appeal with the Armani Hotel on its lower levels and the At.mosphere restaurant on the 122nd floor. Apart from the structure itself, nearby landmarks such as the Burj Khalifa Park and The Dubai Fountain also form part of this downtown complex. The Burj Khalifa is synonymous with the city, as is evidenced by the myriad replicas of its iconic form fitted into souvenir stands and depicted on postcards.

The architect Friedensreich Dunkelbunt Hundertwasser is very well known to tourists for the municipal lodgings he has built in the Löwengasse. His style presents color, nature, and a belief that nothing should ever be even! The suitability of the embellishments to the chimney of the neighboring heating plant was the subject of much discussion in Vienna. Finally, the plant's roof was crowned with a big hat, typical of Hundertwasser's work. It's a very bright, colorful building - well worth a look.
