Built in the 16th century by Diego Beltrán, a nobleman and member of the Royal Council of the Indies, around 1528–1533, on a site previously used on Santiago Street. Its design is attributed to the royal architect Luis de Vega. From 1602 to 1604, it housed the Royal Chancery; later, it served as the residence of the Marquis of Ensenada during his exile. In 1916, it was acquired by the Marquises of Argüeso; in 1950, it passed into the hands of the State and was used as a vocational institute, currently functioning as an educational center.

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! 🌟
