Another incredible UNESCO treasure, this majestic construction is an early example of the exquisite Islamic style that reached its culmination in the most famous tomb on Earth, the Taj Mahal. Dating back to 1632, the ivory-white mausoleum was built to house the tomb of the Mughal emperor's favourite wife and it is located in Agra, a city on the banks of the river Yamuna.

Rolling hills, national parks and state forests surround gorgeous Dungog. Its main street is an urban conservation area. Notable historic buildings include the primary school built in 1843 and designed by colonial architect Edmund Blacket, who also designed the University of Sydney and St Andrew's Cathedral in Sydney. The Dungog Cinema has a Spanish mission-style façade and is the oldest operating purpose-built cinema in Australia.

Plaça Reial, a beautiful square in the Gothic Quarter and one of Barcelona's busiest, most vibrant spots (especially so at night), is known for its many outdoor venues, restaurants, and nightclubs. During summertime, it becomes an even more popular meeting place when open-air concerts take place. A standout feature is the elegant lampposts designed by Antoni Gaudí in 1879—one of his earliest works—featuring intricate details like the city’s coat of arms. Stroll around or sit down with a tasty drink at one of the bars and just enjoy the moment.

Höhenpark Killesberg is Stuttgart’s go-to green space when you want a break from the city buzz. It’s got a bit of everything: a 40-metre spiral tower with city views, a miniature train that loops through the park, and a petting zoo with goats, donkeys, and llamas. During the summer months, the outdoor pool and wave machine are a hit, and there’s plenty of space to picnic or wander through flower gardens.
