This square, more commonly known as Rossio Square, has the usual Portuguese mosaic pattern of black and white cobbles, this time in a wave formation. It really does upset the equilibrium. The square is in the centre of the city of Lisbon and the Column of Pedro IV is in the middle of the square. The building of the Maria II Theatre and the Public Gardens are at the north of the square, a French bronze fountain is another landmark and of course Rossio railway station built in 1886-7 is close by. The Rossio Square is linked to the other main square of the city, the Praça do Comércio, by two straight streets: the Áurea and the Augusta Streets.
