Shortly afterwards, King Carlos III commissioned Francesco Sabatini to build a new gate to replace the previous one as the entrance to the city from the new Paseo de La Florida.
The work was completed in 1775 and Sabatini placed an ornamental fountain next to it, popularly known as the Fuente de los Mascarones.
It consisted of an arch and two shutters (or portholes) and was built of granite and limestone from Colmenar de Oreja.
In front of it there were two buildings that also disappeared: the aforementioned Mascarones fountain, between 1775 and 1871, and the Washerwomen's Asylum promoted by María Victoria dal Pozzo, from 1872 to 1938.
To do this, a replica was made under the direction of the engineer Juan A. de las Heras Azcona, being located in the opposite position to the original, that is, facing the city.
