In 1876 it was decided to demolish the old building and the Pontevedra City Council approved the plans presented by the architect Alejandro Sesmero.

[10] During this renovation work, the original iron skylight of the building, which in 1953 had been hidden behind a Stained glass window with the coat of arms of the province of Pontevedra, was found.

[12] The entrance from the Plaza de España was reserved for institutional events that took place on the first floor[13][14] ( municipal councils, weddings or civil baptisms, speeches, reception of the Three Kings...).

[15] The building belongs to the eclectic style that prevailed at the end of the 19th century with elements and concepts inspired by French architecture.

[16] In fact, as the historian Jesús Ángel Sánchez García discovered, he partially plagiarised the design of the rear façade and interior of a mansion (the hôtel particulier Murat (1850-1864), demolished in 1961, having belonged to Prince Murat and before that to Cécile Furtado-Heine) at number 8 of the former Parisian street of Valois-du-Roule (joined to the street of Monceau in 1868, the mansion was located at number 28) designed by the architects François-Joseph Nolau and Édouard-Emmanuel Convents, adapting it to the required institutional function with the inclusion of the city's coat of arms, the main balcony and the clock at the top.

The columns that frame the entrance are on a large raised pedestal and are crowned by highly decorated Ionic or Roman Corinthian capitals.

[19] The gallery that surrounds the staircase with wide openings, leaded glass windows and the skylight that covers it is particularly noteworthy.

Teucer, the valiant, founded you on the banks of this river, so that of Spain you may be the most beautiful city, the sword of Zebedee crown your kindness; a castle, a bridge, the sea which is your proof of nobility.
