Great Wall of China: Stretching more than 5,500 miles and named one of the greatest wonders of the world by UNESCO in 1987, the Great Wall of China is worth a visit due to its architectural grandeur and historical significance.
Barcelona, Spain: With its beautiful beaches and Gaudi architecture, Barcelona is a popular destination for people around the world. The city is the 16th-most-visited city in the world and the fourth most visited in Europe.
Acropolis -- Athens, Greece: Photos do little justice to the splendor of witnessing the sacred buildings at the Acropolis firsthand.

Venice, Italy: There isn't another city in the world like Venice. Tourists flock there but don't let that stop you from exploring the city's beautiful architecture by boat.
Chichen Itza, Mexico: A perfect day trip from Cancun, the Chichen Itza is the largest of the archaeological cities of the pre-Columbian Maya civilization. It was recently selected as one of the New Seven Wonders of the World.

Eiffel Tower, Paris, France: The quintessential symbol of the City of Light is also the most visited landmark on the planet. At 984 feet, the Eiffel Tower offers majestic views of Paris and is definitely worth a visit.
Leaning Tower of Pisa, Italy: Known worldwide for its unintended tilt to one side, tourists often visit the tower during a day trip from Florence, Italy. Until recent years, tourists were not allowed to climb the staircase inside the tower, due to consolidation work. But people can now again enjoy the view from the tower by climbing its 294 steps.
Pyramids, Cairo, Egypt: One of the great tourist attractions of Egypt or even the world. The Giza Pyramids attract millions of tourists each year. The Pyramid of Khufu at Giza is the only one of the Seven Wonders of the Ancient World still in existence.
