Pazo do Hórreo, Parliament building in Santiago de Compostela, Spain.

The Pazo do Hórreo is the seat of the Parliament of Galicia located in Santiago de Compostela, featuring a rectangular structure with prominent corners. An interior courtyard facilitates circulation through the various functional areas.

Designed by Antonio Bermejo y Arteaga with backing from politician Eugenio Montero Ríos, the building was modelled on the École nationale d'Alfort in France. Construction began on 25 March 1903 to house Santiago de Compostela's veterinary school, which opened there on 2 October 1915. The school closed under Primo de Rivera's military directorate and the building later became a barracks. Acquired from the Ministry of Defence in 1986, it was renovated and began serving as the seat of the Parliament of Galicia on 1 March 1989.

The parliamentary hall features wooden panels and curved benches that reflect the formal nature of legislative work. These elements shape how debates and voting take place inside.

The building stands at Rúa do Hórreo 63, in Santiago de Compostela. As the seat of the Parliament of Galicia, it is a working government institution with restricted access; visits depend on parliamentary sessions and prior authorization. Check opening conditions and access rules before planning a visit.

The exterior fence is made of oxidized steel and creates an optical illusion that appears opaque from most angles but becomes transparent when viewed straight on. This effect is created by the specific arrangement and material of the metalwork.
