The Pazo of Raxoi is the seat of the Town Hall of the city of Santiago de Compostela and of the presidency of the Xunta de Galicia.

It is a neoclassical building, which was ordered by the archbishop of Santiago: Bartolomé Raxoi Losada, in 1766, in order to serve as a seminary for confessors. The French engineer Carlos Lemaur was responsible for the work. On its façade there is a representation of the Battle of Clavijo and a sculpture of the Apostle St. James.

The palace is located on the western side of the Plaza del Obradoiro. To its right is the Colegio de San Jerónimo, which today serves as the headquarters of the Rectorate of the University of Santiago; to the left of the palace is the Royal Hospital of the Catholic Monarchs, now the Hostal.

The site on which the palace of Raxoi was built was previously occupied by the city's prisons, civil and ecclesiastical buildings, and a section of the city wall, which defended the city from the west. The dual ownership of the property led to disagreements between the Bishopric and the City Council.

The palace helped to enhance the Plaza del Obradoiro, which lacked a worthy building on that side, even though the imposing new western façade of the Compostela headquarters had been completed only a few years earlier.

Its style corresponds to a French palatial type developed by François Mansart, ultimately based on Italian models: a long porticoed loggia, with cushioned perpiails, on which the corresponding bodies rise, and embraced by a colossal order.

This pattern was adapted to the Compostela building. On a rectangular plan, horizontality predominates, with the almost 90 m long façade, barely broken by the acroteria and pediments of the crowning, which contrasts with the verticality of the cathedral façade. In the lower part of the façade, there is an asso-portal with twenty semicircular arcades on the sides and five lintelled arcades in the centre. Above this loggia, two upper bodies are developed, both established by attached columns of a giant Ionic order, which start on a pedestal supported at the end of the portico. Between these colossal columns are fifty openings, door-like in both cases, as they provide access to the continuous balcony that runs along the entire façade on the first floor, and to a railing on the second floor. These openings ensure the brightness of the interior rooms.
