Dueñas Palace, Medina del Campo, Renaissance palace in Medina del Campo, Spain.

Dueñas Palace is a Renaissance structure with a square layout, two stories, brick facades built on limestone bases, and an entrance portal featuring decorated columns. The building shows typical 16th-century architectural details with carefully designed elements at the facades and entrance.

Diego Beltrán, an hidalgo enriched in Peru and a member of the Council of the Indies, began building this house in the mid-1520s on a plot on the then calle de Santiago. Its design is attributed to royal architect Luis de Vega. Through the marriage of Mariana Beltrán to Francisco de Dueñas, it passed to the Dueñas family and later to the marquises of Argüeso, who in 1916 planned to move the courtyard and staircase to Madrid. Declared a national monument in 1931, it was acquired by the state in 1950.

The courtyard displays medallions showing Castilian monarchs, created by sculptor Esteban Jamete in the 16th century during the Renaissance. These pieces remain a striking feature and reflect the artistic ambition of that era.

The building now serves as a secondary school, so access to historical sections is limited and mainly possible during school breaks. Visitors should check ahead to ensure the exterior facades and any accessible areas can be viewed.

In 1916 the Marquises of Argüeso bought the palace and planned to dismantle the courtyard and staircase and move them to Madrid; the transfer never happened. The cloister staircase keeps two small statues on corner pillars, and a second, smaller two-flight stair opposite has a parapet carved with the owners' coat of arms and grotesques.
