West of Comercio Square, following Rua do Arsenal, is Praça do Municipio (Municipal Square), a small peaceful square where the City Hall, Appeals Court and Navy Arsenal stand. The City Hall building is a neoclassical palace with an elegant exterior featuring sculptures on the triangular tympanum supported by four paired columns. The interior, which can only be visited on free guided tours on Sunday mornings, is rich in works of art, including a painting showing Marquês de Pombal during the times of the reconstruction of Lisbon. Outside the building is an interesting pillory with a spiral column built of a single block in the 18th century, and crowned with a gilt metal sphere.
