With a private guide or driver, embark on a half-day tour of Lisbon, the city of seven hills, has layers of history dating to occupation by the Phoenicians, the Romans, the Visigoths and the Moors. Visit the heart of the city, Rossio Square, then spend some time in Alfama, the Old Quarter. See the Lisbon Cathedral, with history dating back to the 12th century, and admire views of St. George’s Castle, a Moorish fortification, while catching a stunning panorama over the city from the Miradouro da Senhora do Monte lookout. In Belem, the city's monumental district, walk alongside a pair of UNESCO World Heritage Sites: the stunning 16th century Jeronimos Monastery, and the Belem Tower on the bank of the Tagus River. Enjoy a short stop at the Monument to the Discoveries, celebrating the influential 15th-16th century Portuguese Age of Discovery before a transfer back to your hotel.
