Colosseum
Today, one of the most recognizable symbols, not only Rome, but of Italy. The Colosseum was actually called the Flavian Amphitheater. There once stood a colossal statue next to the monument of Nero, but since he was not liked, and time passed, was most likely melted down.
Today, the amphitheater is better known as the colosseum. Notice that there are 80 entry ways into the monument, each with their own number 1 through 80 (in Roman numerals). These entry-ways lead to specific seating arrangements that were already established by social status and gender. At the highest point, massive pieces of fabric stretched almost the entire length of the structure. They were controlled by knowledgeable sailors that blocked the summer heat with shade, the rain with a roof, and allowed the gentle wind to air out the stadium.
Imagine watching animal hunts in the morning, public executions around noon, and gladiator fights in the afternoon. All of the entertainment was free to citizens of Rome, and they had enough enjoyment for people to stay all day.
