We arrived in Rome yesterday and today was our first day seeing the sights. We decided to just walk today before deciding on more specific tours for later in the week. A total of 12.63 miles according to the GPS.
Trevi Fountain. Nice but not mindblowing.
The Pantheon. This is one of the sites I really wanted to see. The dome was built from concrete nearly 1,900 years ago. You understand the meaning of Dark Ages when you realise it took until the 19th century to recover this level of engineering ability. Definitely mindblowing.
