Vienna's cathedral has survived many wars and is now a symbol of the city's freedom. The Gothic cathedral was first built in 1147 and its most recognizable characteristic, the diamond-patterned tile roof, was added in 1952.
Melk Abbey was originally a palace, and it shows. Home to a Benedictine community from the 11th century to the present day, the current Baroque ensemble was built in 1736.
Hailed by some as the most perfect Renaissance building in the Germanic countries, Salzburg's cathedral has a marble facade, twin symmetrical towers and the font in which Mozart was baptized.
This was originally built in the 14th century as the parish church of the imperial court. Several royal weddings took place here and Hapsburg hearts are preserved in urns.
Built in the 13th century over an earlier church, this small edifice next to the cathedral is interesting for its venerable age and mixture of styles. The semicircular choir features elaborate vaults and nine chapels.
Holy Trinity Church
Constructed in 1694 by the famous Baroque master builder Fischer von Erlach, Holy Trinity Church has a sweeping facade that is among the most excellent examples of the unexaggerated Baroque style.
Alter Dom (Ignatiuskirche)
No longer the cathedral of Linz, the Ignatiuskirche is best known as the Alter Dom (Old Cathedral). It is the largest Baroque church in the city.
Abbey of St. Florian
An impressive example of Baroque architecture, the Abbey of St. Florian is built around the grave of its namesake, the patron saint against fire and flood.
