I love anything older than things in the U.S., which pretty much sums up the rest of the world.
Jordan was weird in that they have ancient history and modern history with nothing in between. ruins 2000 years old from the Nebateans, 1500 years old from the Romans, and the oldest buildings in Amman are from the 1920's.
One of the things that hurts my feelings, is that New Orleans had a huge fire that destroyed almost all of the Quarter. Everything's from the 1800s after that, except Jean La Fitte's blacksmith shop.
I always wished I could see the original Spanish Quarter.
Humans don't think their era is worth preserving.
