Lisbon's Alfama tumbles from the castle to the river and dates back over a thousand years to Moorish times. Surviving the great Lisbon earthquake of 1755, the tangled streets of the Alfama today present a cobbled playground of old-world color. Traditions survive in Fado, the passionate folk music of Lisbon's backstreets.
