The Aracoeli staircase was built in 1348. It leads up to the church of Santa Maria in Aracoeli. According to the Eyewitness travel guide, if you climb these steps on your knees you can win the Italian national lottery.
In the evening, I took a walking tour of Rome with Enjoy Rome. The guide was Italian and an archaeologist. I found the tour to also be a good overview of Rome and the guide very entertaining. Unfortunately, about an hour into the tour, it started to pour and although our guide decided to take a 20 minute break by taking us to a bookstore for shelter, we soon had to return to the torrential rains to complete the tour. Ah well, it made for a memorable first night.
The following set of pictures were taken during this walking tour.
