Portugal is known for its many charming towns, so my friends and I were determined to visit a couple during our visit. Evora was a priority. Like Sintra, it's a UNESCO World Heritage Site and an easy day trip from Lisbon. As soon as we arrived, we popped into the tourist office for a map of recommended sites, but we quickly realized that our time would be best spent by roaming around the town without much forethought. More than 2,000 years old, Evora feels like a walking history lesson. Beats the classroom, and this coming from a self-professed nerd who always sits at the front of the class.
