The tiles in this square are meant to simulate the movement of the waves in the sea. (Lisbon is a city that overlooks the sea.) This picture was taken our first day as we rode a tour bus on the Belem Line in order to get oriented to the city (while recuperating from a sleepless night on the plane). The weather was mild, the skies sunny, and the buildings painted in lovely pastel blues, purples, light coral colors and various shades of yellow. Buildings were a blend of old and new.
