Goyeneche Palace, Nuevo Baztán, Baroque palace in Nuevo Baztán, Spain.

Goyeneche Palace is a Baroque building in Nuevo Baztán with a rectangular layout, two stories, and a square tower at the northwest corner, constructed in stone and covered with plaster. The structure served as the center of a larger complex that combined residential, religious, and production spaces.

Juan de Goyeneche commissioned the palace between 1709 and 1713 as part of an ambitious project to develop industrial manufacturing including glass and textile production. This undertaking was among the first attempts in Spain to integrate modern factory work with planned urban development.

The palace was designed by José de Churriguera and showcases Spanish Baroque architecture influenced by Juan de Herrera's style. The attached Church of San Francisco Javier forms an integral part of the complex and shapes how visitors experience the central plaza.

The palace cellars, built for storage, now hold an interpretation centre, and guided tours of the palace are offered. The complex stands beside the church of San Francisco Javier, with two squares framing it front and back. The palace was reported in 2007 to be in a poor state of conservation, and a proposed art-gallery use with the Carmen Thyssen-Bornemisza collection was put on hold.

The palace was the centerpiece of a planned grid town with geometric layout, an unusual concept for early 18th-century Spain. This design was inspired by economic reform ideas and attempted to merge traditional Spanish town development with rationally planned design principles.
