In Europe, people are very proud when there is a building that's, say, 800 years old - and rightfully so. Thereby Europe beats the USA by far, for in America older than two centuries has to be considered ancient. However, Europe - including Rome and Athens and in fact all of Greece - without a doubt loses to Egypt - and in Egypt there is one town that stands out like no other: Luxor - which people often call "the World's largest Open Air Museum". This name is more than justified.
Luxor has an abundance of ancient monuments that blows all proportions, and virtually all of them were built around the beginning of the second millennium BC, hence around 4000 years ago.
Obviously, Luxor is highly attractive for tourists - so Luxor International Airport offers flights to many countries. Luxor is actually more than a big museum: it is also a city with a population of 376 thousand people. Of course, tourism is its main economic branch, but far from the only one.
