This building was designed in 1909 at the request of the industrialist and merchant Juan Romero Rodríguez del Villar. He bought the Wallace fountain for the city at the 1889 Universal Exhibition in Paris, which now stands in the Reina Sofía Park.

In Casa Romero, Rodolfo Ucha unleashed his imagination in the decoration of the façade of this building, which opens onto three different streets in the shape of an L. It is one of the architects most purely modernist and most elaborate works.

The interior layout of the building is traditional, with an attic added in the 1940s and a ground floor for commercial use that has undergone various modifications since the 1970s.

The best way to observe Casa Romero is from in front of the Post Office building, where you get a good view. Each of the three façades has different proportions but a formal unity is maintained through the use of repeated elements, such as the stone balconies, the horizontal mouldings between the windows, the wrought-iron oriel windows, the cornice supported by geometric corbels and the numerous mascarons with womens faces.

The two corners of the building have cylindrical-shaped bay windows with undulating forms adorned with vegetal decoration and openwork parapets. This was a way of reclaiming the corners as useful spaces and even to show the luxury of a building with the appearance of an urban palace.
