Lisbon
It was from historic Lisbon, built on seven low hills beside the wide Tagus estuary, that some of Europe's greatest explorers set sail in pursuit of the riches that built Portugal's former global empire in the New World, Africa and the Indies.
Memories of a glorious past linger amid the grand avenues and elegant squares of the attractive capital's 18th century lower town - a vivid contrast with the colourful honeycomb of cobbled streets in the old Moorish Alfama quarter and the bohemian mood of the hilly Bairro Alto.
