This futuristic plaza is one of the most complex and ambitious construction projects ever undertaken in Australia, serving as Melbourne’s civic centre with cafés, restaurants, an amphitheater and several museums such as the Ian Potter Centre that showcases Australian art. There’s also a farmers market every Friday and a book market on Saturdays.

Georgetown feels like a little world of its own in D.C., with cobblestone streets, old brick buildings, and a mix of shops and restaurants. You can wander along M Street and Wisconsin Avenue for over 450 options — from coffee shops to trendy boutiques — or grab a bite along the waterfront. It’s a popular spot for students and visitors alike, and walking through the neighbourhood gives a real sense of the city’s history.

The United States Capitol dominates the eastern end of the National Mall on Capitol Hill — its dome, completed during the Civil War, is hard to miss. The Capitol is the seat of the United States Congress, and it has been a center of American politics since 1800. Inside, the Visitor Center walks you through its history, shows off its art collection, and explains how the legislative branch works. Free guided tours are available, but booking ahead is a good idea — lines can get long, especially in peak season.

One of Amman's most entertaining attractions is the Royal Automobile Museum, mostly containing (nearly a hundred!) vehicles from the collection of late King Hussein of Jordan. Models spanning the second half of the 20th century make for an interesting look around, the latest hit addition being the very vehicle used in the filming of acclaimed "The Martian".
