The centrepiece of the square (and the city), is the Leal Senado, a white washed building with wooden, green windows, wrought iron balconies and flowers hung across its façade. Built in 1784, the building was where the Portuguese plotted their conquest of Asia. It wasn’t to be, and today the building houses the Mayor’s Office and a public library.
The name Leal Senado means Loyal Senate, a name bestowed on the building when constructed, thanks to the Macau administrations refusal to recognise Spain’s occupation of Portugal in the 17th century. You can still see the loyal inscription added to the entrance hall at the bequest of King Joao IV. Also worth seeing are the quintessentially Portuguese, blue, mosaic tiles that line the staircase leading up to the library.
