students in front of Alhambra

So excited that our MATH 215 Mathematics and Art course is in Spain seeing the mathematics behind art in several cities.  In this picture the group is at the Alhambra, a 13th century Moorish palace in Granada Spain which has beautiful geometric mosaics..  This place has an interesting history:  It was originally constructed as a small fortress in 889 on the remains of Roman fortifications, and then largely ignored until its ruins were renovated and rebuilt in the mid-13th century by the Emirate of Granada.  It then became a royal palace and then a royal court.
