#2 St. Stephen's Cathedral Vienna’s Stephansdom (also known as St. Stephen's Cathedral) is kind of a big deal. As the national emblem of Austria, it attracts over 1 million visitors every year. And rightfully so – at over 800 years old, it’s home to some of the country’s most interesting historical and architectural sights. The High Altar, which took seven years to build in the 17th century, is just one of 18 altars inside the impressive Gothic and Romanesque structure. The red marble tomb of Emperor Frederick III is decorated with more than 240 statues - that's 6.667 statues for every year of his reign as Holy Roman Emperor. If your tastes extend to the more macabre, visit the catacombs, built during the 1735 Bubonic plague they're, erm, 'home' to over 11,000 skeletons. 4.4 (365 reviews)

#5 Roman city Carnuntum Carnuntum was an important Roman world city on the border of the Roman Empire from the 1st to the 4th century AD. Due to its militarily important position for securing the border and its proximity to major trade routes, Carnuntum developed into the capital of the province of Upper Pannonia with a population of around 50,000. Bringing history and basic scientific research to life is the goal of the Roman City of Carnuntum. The Roman Quarter with reconstructed ancient houses, the amphitheaters and the Carnuntinum Museum as the treasure house of Carnuntum bring the ancient world back to life. 4.6 (10 reviews)

#7 Melk Abbey Melk Abbey is a remarkable Benedictine abbey, towering over the town of Melk in Austria's Wachau Valley. You might look at the abbey's Baroque grandeur and wonder if it's all a little excessive for people of the cloth. The abbey you see today was actually built in the early 18th century as a royal palace, on the site of an ancient monastery. The abbey is well known for its library, which houses over 100,000 rare and valuable books. The main hall shows off just a percentage, but you certainly get the idea as you gaze at 16,000 volumes and a wonderfully frescoed ceiling. You can take in centuries of art and religious antiquity on a guided tour of this magnificent monastery. 4.9 (8 reviews)
#8 Vienna City Hall The Wiener Rathaus is the spectacular city hall of Vienna, situated on Rathausplatz in the Innere Stadt district. This neo-gothic style building was constructed between 1872 and 1883 and it's now the Mayor of Vienna's office. It's the most important non-religious building in the city, and one of the most striking, which is why it often hosts press conferences, concerts and balls. 4.4 (15 reviews)
