One of the Seven Wonders of the World, the Great Wall is an impressive feat of engineering. The Wall is the product of 21 centuries of building and rebuilding that began in the 5th century BC, and was used to protect the Empire of China from Xiongnu attacks.
Although sections of the current wall, which dates back to the Ming Dynasty, are in total disrepair, near tourist centers it has been well preserved and even reconstructed to give visitors a glimpse of its former glory.
The Eternal City is filled with some of the most stunning and iconic architecture in the world. Layers of Ancient Roman, Medieval, Renaissance and Baroque buildings are to be seen at almost every turn. However, no trip to Rome is complete without taking in the Coliseum, the Roman Forum, the Pantheon, the Circus Maximus, the Arch of Constantine, Fontana di Trevi and at least one of the many historic piazzas throughout the city.
Dotted all throughout Europe there are thousands of Medieval and Baroque castles that conjure up images of fairytale princesses and chivalrous knights. They were not only built as protective fortresses but also as the homes of feudal lords and kings that showed their wealth and status. Some of the most impressive examples include Germany’s Neuschwanstein Castle, France’s Palace of Versailles, Ireland’s Blarney Castle, Sintra Palace in Portugal, Turkey’s Topkapi Palace, Prague Castle in the Czech Republic and Leeds Castle in England.
