Go down the winding Calçada do Ferragial that takes you to the 17th cent. Corpo Santo Church then turn left onto Rua do Arsenal, leading to Praça do Município, and the Lisbon Town Hall, built in 1774 and subsequently undergoing major modifications. Two blocks east lies one of Europe’s outstanding city squares, the 18th cent. Praça do Comércio.
