The downtown of Lisbon also known as Baixa Pombalina, was totally rebuilt after the 1755 earthquake by Marquês de Pombal and includes the Terreiro do Paço, Rossio and Praça da Figueira.
The lower part is formed by a set of perpendicular streets, being the central one Rua Augusta.
On the end of Rua Augusta, there is a wonderful arch which leads to Terreiro do Paço.
All the buildings in this area have a similar architecture (Pombaline style), with 4 floors, with ground floors used for shops and the upper floors for housing.
This is truly the hearth of Lisbon.
