Walking around Cortona's narrow, medieval streets quickly becomes an exercise in creative composition as the sun aligns itself between the tall buildings. Angular, abstract shapes are created by the strong shadows, like pieces of a giant puzzle. The light is constantly changing the apparent shape of the architecture, providing a slowly shifting light show from dawn to dusk.
It's the sort of place where a photographer or a painter or anybody with an appreciation of light would enjoy just sitting and watching. Perhaps that's why there are so many bars and cafes with al-fresco tables. It's not only because dining outside is generally more pleasant, it's also because nobody would want to be indoors when the sun is breathing life into the walls outside in such an extraordinary way.
