AFTER THE EARTHQUAKE OF 1755
1755 marks a period of development. The earthquake (on November 1, All Saints Day, at 10 am), and the fire that followed, devastated two thirds of all the streets and have destroyed three thousand twenty thousand existing home.
The earthquake covered the whole area of downtown, the neighborhoods of the Castle and the Carmo area, i.e the most intensely urban areas of the city.
In its place would be born to Lisbon Pombal, with an urban subject to fixed rules and a pragmatic scientism that causes admiration worldwide. The main driver was the Marquis of Pombal, the Prime Minister , assisted by architects and engineers, Manuel da Maia, Eugénio dos Santos and Carlos Mardel (1755-76).
The plan, without a doubt innovative, based on a planned direction lined streets, whose architectural options based on building regulations, taking into account basic concepts of resistance to seismic actions.
The urban system obeyed strokes composition axles where the symmetry was compulsory subject, and we want it usually highlight the extremes, monuments or statues: Rua Augusta with the triumphal arch, through which, on its axis, placed the statue of D.José.
Pombal created incentives of interest to the new commercial bourgeoisie class.
The northern Rossio opens the “Public Garden” (1764), playground of the bourgeoisie. It was a latticed garden with waterfalls, ponds with fountains and gazebo, which was later open to new avenues and future neighborhoods built by a bourgeoisie on the rise. From 1780 appears the public lighting of the city and in 1801 the streets have been given the name displayed.
