Statistics Portugal Head Office was classified as a monument of public interest in April 2013. This classification reflected the official criteria, which pertain namely to the character of the “good”, its aesthetic value and architectural design, technical and intrinsic materials.

The building was designed by the architect Porfírio Pardal Monteiro and inaugurated in 1935. It was one of the first public buildings designed expressly to meet a specific purpose: to install the newly created Statistics Portugal – INE.
