Ephesus
The second one is Ephesus' grand theatre which had the capacity of 25.000 spectators. It was not just a place of art also as we know it was used for animal and gladiator fights.  With its great dimensions it makes one think about how small my moment in time really is.  It's one of the sacred ruins of Ephesus, according to the Acts of the Apostles (19:23-41), the theater was the site of the "riot of the silversmiths" in which those who made silver figures of Artemis the pagan godess of the city rioted because Paul's preaching was bad for business.  In the 1st century AD, the Apostle Paul spent over three years in Ephesus and he sermonized many times, disapproving pagan worship, in this theater.
