Valladolid Town Hall, Art Nouveau municipal building in Plaza Mayor, Valladolid, Spain.

Valladolid Town Hall is a rectangular building of 2,598 m² on the north side of Plaza Mayor, with a basement and three upper floors, corner towers and a taller central clock tower bearing the city coat of arms. Its eclectic, Beaux-Arts character with Renaissance inspiration follows the Monterrey palace in Salamanca; the architect Enrique María Repullés y Vargas used granite from Campaspero and Villanubla for the plinth and pressed brick for the facade walls, except the central section.

The old town hall, begun in 1562 and finished in 1577, was demolished in 1879; its remains went into the waterfall and pond of Campo Grande. A 1880 competition chose Antonio Iturralde, but works stalled and stopped in 1894. After Iturralde died in 1897, Enrique María Repullés y Vargas won a draw among six architects, tore down what had been built and designed the present eclectic, Beaux-Arts building, opened on 19 August 1908.

The balcony over the Plaza Mayor is where the new building was inaugurated on 19 August 1908 with an institutional ceremony and a mass celebrated from it. Inside, the reception hall opens onto that balcony, with stained glass showing figures from the city's history and a full-length portrait of Pedro Ansúrez, first lord of the town.

The building is centrally located on Plaza Mayor and easily accessible on foot from surrounding streets. Visitors can appreciate the architectural details from outside and view it from multiple vantage points around the square.

On 18 July 1936, when the army rose against the Second Republic, the building was attacked from the Plaza Mayor; about 53 bullet marks remain on the facade, concentrated around the window of the office of the then socialist mayor, Antonio García Quintana.
