This is a stone theater structure located right next to the Acropolis of Athens. It was built in 161 AD by Hoerodes Atticus in memory of his wife. It has a total capacity of 5,000 audience members, which is a huge venue for the time period it was built. Today, Greece still uses this location for concerts. I didn’t get to have that experience, but I bet it would be outstanding. How couldn’t it be outstanding?
