The current city hall, seat of the Câmara Municipal (municipal chamber) of Lisbon, was constructed between 1865 and 1880.The neoclassical structure, designed by architect Domingues Parente da Silva, is one of the most elegant buildings in Lisbon. The main facade is decorated with sculpted ornaments and pediments. Its central pediment with relief sculptures is supported by double Corinthian columns. Inside is a large atrium with a magnificent marble staircase with large lampposts, designed by José Luís Monteiro. The city hall is not only an important architectural masterpiece, it is also a significant political symbol. On October 5, 1910, the Portuguese Republic was proclaimed from the balcony of the city hall, an event that is celebrated annually at the square.
