Tejo Power Station (architectural ensemble)

It was built in 1909 and based on a project by engineer Lucien Neu, with architectural execution carried out by Charles Vieillard and Fernand Touzet.

The defining features of this old power plant were the slender chimneys, one in brick and one in iron, in an inverted conical stem shape.

The north and south facades of the central nave, where the generators were located, were decorated similarly to other iron architecture structures, such as train stations and markets, with modernist influences recently seen in Portugal.

These were divided into three sections separated by pilasters, small cogged friezes that ran horizontally along them and, crowning the structure, a large broken pediment.

The central section, larger than the sides, stood out due to its large bay spanning the entire facade from the base to the top, entering the pediment and forcing it up.

The old Boiler Room is made up of four industrial naves, three of them identical and the fourth on a larger scale, covered with gable roofs creating a single diaphanous space inside.

Under all this, a flat base where the brick is hidden, decorated with low arch frames simulating openings, “supports” the rest of the entire facade.

The top of the facade, also formed by a broken pediment, displays decorative frames made from brick, simulating Lombard bands.

The main body displays large windows that end in semi-circular arches with a keystone, outlined with a frame that runs the entire length of the facade.
