Parque de Lamuza, Llodio, Baroque palace in Llodio, Spain.

Lamuza Palace is an 18th-century baroque-classicist building in Llodio, enlarged in the 19th century by architects Francisco de Cubas and Francisco de Mendoza and in the 20th century by Luis de Landecho. The original square structure has a ground floor, main floor and attic, with thick masonry walls, ashlar corners and window surrounds, and oak timber framing. Its only facade ornaments are the brackets under the balconies, the wrought-iron railings and a family coat of arms, now replaced by the town's.

The original square building was raised in the early 18th century by the mayorazgo of Orue in a sober classical-baroque style, with thick masonry walls and oak timber framing. In 1876 Estanislao de Urquijo y Landaluce, first Marquis of Urquijo, bought the house to use as a summer residence. Francisco de Cubas y González-Montes and Francisco de Mendoza y Cubas enlarged it in eclectic and regionalist styles in the 19th century, and Luis de Landecho Jordán de Urríes worked on it in the 20th.

The palace was long the centre of Llodio's social and political life, largely through the influence of the Urquijo family, among the most powerful in the Basque Country in their day. The family crest on the facade has been replaced by the town's own coat of arms.

The palace stands inside Lamuza Park, a 94,490 m² estate that surrounds the 7,784 m² residential complex. The building itself is not open as a museum; after restoration it is to house a Basque-language school, a children's play centre and a youth centre. Visitors cross the grounds on foot, and the park is the main public space of Llodio.

The original 18th-century building had a square plan with a ground floor, main floor and attic, and its frame was made of oak wood. Its only facade decorations were the corbels supporting the balconies, the wrought-iron railings and the family coat of arms, now replaced by the town's own.
