Book your timed admission ticket for Stonehenge, one of the world’s most famous prehistoric monuments.

1. Stonehenge

It’s more than just a pile of rocks: Stonehenge remains shrouded in mystery ever since its appearance in England over 4,500 years ago. The prehistoric monument has puzzled archaeologists and scholars alike, with lots of interesting theories (but no real consensus). Nobody seems to know much about why it was built, or how, for that matter. Neolithic builders apparently lugged these giant stones over 200 miles from Wales. It’s only fitting that you travel just as far (by bus, don’t worry) to see these strange standing stones for yourself.
Climb 463 steps to the top of the cupola for panoramic views of Florence.

2. The Florence Cathedral

Construction of this stunning Italian cathedral began way back in 1290, and took over a hundred years to build. With its giant brick dome and unique design, it’s remained one of Tuscany’s major attractions. See why these three massive buildings were named a UNESCO World Heritage site on a long and winding climb up the Dome’s interior. 
Save precious time at the Eiffel Tower with a priority-access ticket to the second level.

3. The Eiffel Tower

Is there a more iconic emblem of France than the Eiffel Tower? Berets, striped shirts, and the Parisian penchant for tobacco aside, the Eiffel Tower is a definite symbol for all things French, and a must-see place to visit on your next trip through Europe. A cruise down the Seine with bubbly in hand after you’ve seen the city from the top doesn’t hurt either. Salut!
Take a cruise and see the sights of London from a different perspective.

4. The River Thames

The River Thames is both the longest river in England and a major symbol of London’s long and winding past. Ride the waves on a cruise from Westminster to Greenwich and learn more about London along the way. There’s a lot to see here — like a lighthouse and a wall covered in bright street murals that are only visible from the water. The river also provides about two-thirds of the city’s drinking water: don’t worry, it’s a lot cleaner now than it was back in the 19th century.

Offering breathtaking views over the German capital, the TV Tower cuts a striking image against the Berlin skyline.

8. The TV Tower

It’s funny to think that the TV tower, or Fernsehturm, was constructed by the East German government as a symbol of communist power.
