January 16, 2026, Iglesia de Santa María la Mayor de la Asunción de Tordesillas

Declared a Site of Cultural Interest (BIC) on December 7, 1983, this church is located in the heart of Tordesillas (Valladolid), one of the town's most iconic landmarks and the largest in the entire municipality. It is believed to have been built on the site of the former Tordesillas mosque. The main construction took place between the 16th and 17th centuries, with additions continuing into the 18th century. The church combines Gothic elements (the apse and the lower sections of the tower) with Neoclassical renovations inspired by El Escorial. Today, it serves as the headquarters for several Holy Week brotherhoods, housing processional floats such as the Virgin of Solitude and the Christ of Mercy.

It was built between the late 12th and early 13th centuries by Commander Fernán (Hernán) Rodríguez de Valbuena, becoming a funerary chapel for the Order. For centuries, it served as a fortified church overlooking the Duero River, and was linked to the now-vanished castle and other medieval chapels in the town. It suffered several collapses in the 19th and 20th centuries, until the original ruins had practically disappeared; the current structure is the one dedicated to Santa María del Castillo (Saint Mary of the Castle).

Hermitage of Santa María del Castillo (also known as the Hermitage of Santo Cristo or the Church of the Order of Saint John) in Castronuño: Located on Alto de la Muela, on the banks of the Duero River in Castronuño (Valladolid). A medieval building originally linked to the Military and Hospitaller Order of Saint John of Jerusalem, which established a commandery here.

The building, constructed between the 16th and 18th centuries, began in the Gothic style and finished in the Neoclassical. Another striking feature is its tower, the tallest in the city. The Baroque-era organ is considered one of the finest in the region, both for its design and its state of preservation.

The medieval bridge over the Duero River, with its perfectly aligned arches, connects the historic center to the opposite bank. The monumental skyline of Tordesillas, highlighting the Plaza Mayor, the Casas del Tratado (Houses of the Treaty), and the Monastery of Santa Clara, all framed by reddish rooftops and the silhouette of the Church of San Antolín. The Duero River winds beneath the bridge, its reflections shifting with the changing light, creating a highly photogenic scene. Natural surroundings: riverside vegetation and, in autumn, golden hues that enhance the scenery.
