This oldest area of the city is located between the Lower City and the Upper City of Salvador, which are connected by the Lacerda Elevator. In the Upper City, streets, hills and alleys start at Praça Tomé de Sousa (better known as Praça Municipal) and are access routes to Barroquinha, Avenida J.J. Seabra and Avenida Sete de Setembro. In the Lower City, Praça Cairu (now Praça Maria Felipa) is part of the city's banking sector and the port area of Comércio, where the old Customs building is located, where the Mercado Modelo would be relocated after the fire of 1969.
