Mr. Policarpo of Mendoza and Rodríguez was born in Baiona in 1706.He was a Knigth of the famous Order of Carlos III in 1781. He practised the literary degree in Santiago, and was vicar – general of Oviedo and of its bishopric, and prebendary of that cathedral.
A priori, in 1751, he was named Dean of the metropolitan church of Santiago. He was the founder of the nunnery of that city, of the children school of Mañufe, and of the religious services at 11.00 hours celebrated daily in the old Colegiata of Baiona and in the Chapel of Rosario. Mr. Policarpo left money to assist these foundations, and to give a dowry to the orphans of Mañufe and Baiona. He also left money to his relatives, and for those who were not his relatives, he provided two posts in the nunnery of Santiago which they could occupy whenever they wanted.

Mr. Policarpo of Mendoza was protector and founder of the School Chapter of Baiona. In 1768 he started to build the house later known as the Dean house, in the Plaza of La Fruta, nowadays known as Pedro of Castro; there was an old house here that he bought to Mr. Francisco Antonio of Araujo and Mosquera.
On the 6th of June, 1780, Sebastian González Nandín, inhabitant of Baiona and residing in Cádiz, made a donative of 12 spinning wheels in order to distribute between the families who made use of them, and of 750 reals in order to hire teachers to teach how to use them.
This information was told to Mr. Policarpo of Mendoza, in order to make him to contribute to this labour; he accepted with pleasure, as he thought it was a pious work with public validity.
In 1851, Miss Dolores Zúñiga of Navia got married Juan Rodríguez, and she received from the steward and administrator of the Municipal Council Charity of Baiona the quantity of 850 reals, as a relative of the Dean of Santiago, Policarpo of Mendoza.

It is ignored how the income of this foundation dissapeared, to those inhabitants of Baiona who were poor and honest. Mr. Policarpo of Mendoza died on the 17th of March, 1794, and was buried in the Cathedral of Santiago.

The house was finally built in 1769, season known as the Hunger Year.
This immovable named by then the Dean house or the Mendoza House, was renamed in 1930 as the House of Besada and Isla, and time before as the House of Pedro Castro, the Verísimas, and nowadays as the Hotel and Restaurant Pazo of Mendoza and María of the Espíritu Santo Rodrigo: he was inhabitant of Mañufe, and was the court clerk (insolidum) in the Council of Gondomar for a long time, by titles of his Majesty; she was born in the House of Moreira, nowadays the Pazo of Mendoza in Mañufe.

It is said in the chronicles that Policarpo of Mendoza, illustrious son of Baiona, was always willing to do his best. On the 16th of May, 1783, he paid the glass windows of the harum – sacrum of the Colegiata of Baiona, situated in the northern side of the temple.
