The building that currently houses Navajas Town Hall was constructed, as indicated by the original plaque dating from 1780, with surplus public funds from the municipal accounts. The site was previously occupied by the old house of the Lord, where the Lord of Navajas, Count of Cirat and Villafranqueza, resided.

The black marble plaque that can be seen on the façade of the building that currently houses the offices of Navajas Town Council bears witness to the construction of what was then known as the Casa Capitular (Chapter House). The construction of this building appears to have been financed with the profits obtained from the agricultural exploitation of the land that was legally known as Propios Comunales, that is, belonging to all the residents, and which was mainly the land of the LLano that, years later, would be sold.

The inscription commemorating the construction reads:

‘THE YEAR 1780 21 OF THE KINGDOM OF OUR CATHOLIC MONARCH Mr. Dn. CARLOS III, MAY GOD SAVE HIM MANY YEARS, WAS COASTED WITH THE SURPLUS OF THE PROPERTY OF NAVAJAS’
