Most Lisbon Free Walking Tours will take you through three main areas in the city center — the bohemian Bairro Alto, the Chiado area, and Baixa. In these charismatic quarters, you will discover the must-see landmarks of Lisbon, which include the Castelo de Sao Jorge, Casa dos Bicos, Carmo Church, Santa Justa Elevator, Rossio Square, Dom Pedro IV Square, Sao Domingos Church, the Arco da Rua Augusta, the Mirador de Portas do Sol, Vasco da Gama Bridge, and the amazing Praça do Comércio. Also, in the Barrio de Belem area, you cannot miss Belem Tower, 25 de Abril Bridge, the Plaza de Alburquerque and the Jeronimos Monastery, among others. Art lovers would want to visit the famous Calouste Gulbenkian Museum, as well as many other quirky galleries in Chiado. Finally, you cannot leave Lisbon without riding one of the famous brightly colored trams that cross the city. You will feel like travelling back in time!
