Lisbon is a calm, compact jewel of cobbled streets and tile-clad buildings on the Tagus estuary. The oldest part of the city, the warren streets that make up the Alfama, sits below the spectacularly sited Moorish Castelo de São Jorge. On the other side of the Ponte 25 de Abril lays Belém, the suburb from which Portugal’s great navigators set sail. Lisbon is a place to wander the narrow backstreets, stroll the beautiful waterfront and climb the many hills to take in the views.
