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).

The Alcázar of Toro is a historic fortification located in the town of Toro (Zamora, Castile and León), with great heritage and scenic value. It was built in the 10th century during the Christian repopulation, as part of the defensive system against Muslim incursions. It was reinforced in subsequent centuries, especially in the Middle Ages, when Toro acquired strategic importance in the Kingdom of León and later in Castile. It played a prominent role in the War of the Castilian Succession (1475), in the famous Battle of Toro between supporters of Isabella I of Castile and Joanna la Beltraneja.

The inspiration for the Collegiate Church came from the Cathedral of Zamora, and its design also influenced other buildings, such as the Old Cathedral of Salamanca. Construction began in the 12th century under the auspices of the kings of León. It is one of the most characteristic examples of Romanesque in its transitional phase. The works extended over an unusually long period, from the last third of the 12th century to the middle of the 13th. The collegiate church was built in two stages: the first included the side portals, walls and layouts, while the second focused on the roof and a dome with attached towers. If you ever have the opportunity to visit Toro, don't miss the opportunity to explore this wonderful collegiate church. It is a true historical treasure! 🌟
