Berlanga de Duero - Santa María del Mercado

Berlanga de Duero is located in the shadow of the castle of the same name is located. It was part of the Caliphate's defense system and was conquered by the Castilian king Fernando I of Castile in 1059. In the 16th century, the Marqueses de Berlanga, on whom the city depended, promoted a profound urban reform. They built the Collegiate Church, the Palace of the Marquises and the Hospital of San Antonio. In 1660 the castle caught fire and was abandoned.

After papal permission had been granted in 1513 to convert the existing small church of Santa María del Mercado into a collegiate church, over the years 1526-1530 the old church was demolished and completely rebuilt as a representative collegiate church.

In December 2022 the church was under reconstruction, but we could see the interior.
