Medieval World

In the 19th and early 20th centuries, some writers claimed that lists of wonders of the world have existed during the Middle Ages, although it is unlikely that these lists originated at that time because the word medieval was not invented until the Enlightenment-era, and the concept of a Middle Age did not become popular until the 16th century. Brewer's refers to them as "later list[s]" suggesting the lists were created after the Middle Ages.
Many of the structures on these lists were built much earlier than the Medieval Ages, but were well known. These lists go by names such as Wonders of the Middle Ages (implying no specific limitation to seven), Seven Wonders of the Middle Ages, Medieval Mind and Architectural Wonders of the Middle Ages.
Typically representative are:

• Stonehenge
• Colosseum
• Catacombs of Kom el Shoqafa
• Great Wall of China
• Porcelain Tower of Nanjing
• Hagia Sophia
• Leaning Tower of Pisa

Other sites sometimes included on such lists:

• Taj Mahal
• Cairo Citadel
• Ely Cathedral
• Cluny Abbey
