The Top 12 Things Not to Miss When Visiting Vienna, Austria

Once the Summer residence of Prince Eugene of Savoy (1663-1736), the stunning Belvedere Palace is now undoubtedly one of Vienna's most visited historic sites. Located in the city's third district, this stately residence houses the world's largest collection of paintings by Gustav Klimt, as well as other distinctive treasures.

And while you could explore the inside of the palace for days on end and still just scratch the surface, brace yourself, because the outside gardens are just as spectacular!

Serving as the second-oldest church in the city, St. Peter's is another historic site that shouldn't be missed when in Vienna. Also referred to as the Peterskirche, the design of this Baroque Roman Catholic cathedral was inspired by the St. Peter's Basilica of the Vatican in Rome, Italy.

Although the outside detail is opulent enough to hypnotize anyone, be sure to head inside to take in the rich interior filled with golden stucco, as well as the astonishing turreted dome.

For years, the lovely shops nestled throughout Old City have been bringing forth delightful experiences for both local residents and visitors, and with good reason. Offering everything from stylish clothes to vintage keepsakes, there's no doubt you'll find a handful of souvenirs here.

All the pizzas are baked to perfection in a spinning oven shaped like a gigantic disco ball!

Plus, this Italian-inspired pizza joint is located in the trendy sixth district known as Mariahilf, which makes for the perfect post-meal stroll.

The splendid architectural design of Vienna's City Hall will make anyone's jaw drop. Built in 1883, this monumental building (also known as Neues Rathaus) now houses the office of the Mayor of Vienna, as well as the chambers of the City Council. What's more? Visitors can join free weekly tours that provide close-up looks at numerous state rooms.

Another notable spot to visit is the Austrian Parliament Building. With an outside facade so rich in detail, many people tend to forget this is the landmark where all the laws of Austria are crafted and put into place.

But if you're on a time crunch and looking for something on the go, consider a tasty trdelník. Locally known as chimney cakes, this rolled, doughy pastry first made its appearance in Prague years ago, but can now be found all throughout the streets of Vienna. And as expected, it's delicious!

Another can't-miss attraction while in Vienna is the gloriette perched high on the hill at the Schönbrunn Palace. Dedicated as a monument for peace, this structure is absolutely breathtaking to witness in person, and is one of the best-known gloriettes in the world.

What makes this particular gloriette unique is its multiple floors and lateral arched arcade wings. The flat roof serves as an observation deck for visitors, which provides a wonderful view of the palace and city, as pictured above. Of course, once you've taken in the sweeping vista, you'd be doing yourself a disservice if you didn't also explore the palace itself.

When making your way there, don't forget to stop by the gardens and infamous tree tunnel.

Thanks to its manageable size and efficient public transportation, getting around Vienna is pretty much a piece of cake. But let's say you're looking for a more unique way to explore the city — you know, besides via bus or bike. If so, consider signing up for the Hotrod Tour.

Not only will you be able to get behind the wheel of a teeny-tiny soap-box car and see the city from a new perspective, but it'll be an experience you'll never forget!
