The 'Seven Wonders of the World' (or the Seven Wonders of the Ancient World) is a widely-known list of seven remarkable manmade constructions of classical antiquity. It was based on guide-books popular among Hellenic sight-seers and only includes works located around the Mediterranean rim. Later lists include those for the Medieval World and the Modern World.

The Greek category was not "Wonders" but "theamata", which translates closer to "must-sees". The list that we know today was compiled in the Middle Ages—by which time many of the sites were no longer in existence. Since the list came mostly from ancient Greek writings, only sites that would have been known and visited by the ancient Greeks were included. Even as early as 1600 BC, tourist graffiti was scrawled on monuments in the Egyptian Valley of the Kings.
Antipater's original list replaced the Lighthouse of Alexandria with the Ishtar Gate. It was not until the 6th century AD that the list above was used. Of these wonders, the only one that has survived to the present day is the Great Pyramid of Giza. The existence of the Hanging Gardens has not been definitively proven. Records show that the other five wonders were destroyed by natural disasters. The Temple of Artemis and the Statue of Zeus were destroyed by fire, while the Lighthouse of Alexandria, Colossus, and Mausoleum of Maussollos were destroyed by earthquakes. There are sculptures from the Mausoleum of Maussollos and the Temple of Artemis in the British Museum in London.

Seven Wonders lists about the Middle Ages
Seven Wonders lists about the Middle Ages are existing historical lists for which there is no unanimity of opinion about origin, content or name.[1] These historical 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". The lists are more properly seen as a continuing type or genre in the Seven Wonders tradition than a specific list.
It is unlikely the lists originated in the Middle Ages. Brewer's calls them "later list[s]"[2] suggesting the lists were created after the Middle Ages. This is supported because the word medieval was not even invented until the Enlightenment-era, and the concept of a "Middle Age" did not become popular until the 16th century. Further, the Romanticism movement glorified all things related to the Middle Ages, or more specifically anything pre-Enlightenment era, suggesting such lists would have found a popular audience in the late 18th and early 19th centuries. Some items found on some of the lists are not technically from the Middle Ages (according to modern historical standards), but we know the lists were not created by modern medieval historians, so such standards did not apply
