Henares or Cuenca) or in union with other buildings, as in Seville. It is similar in design to Brussels Cathedral. History of the cathedral Romanesque building of the 11th century Burgos became a bishopric in 1075 by the king Alfonso VI of León and Castile "the Brave" on authority of Pope Gregory VII, giving it a canonical continuation with the episcopal tradition of the diocese of Oca, whose prelate was in 589 already recorded as a signatory to the Third Council of Toledo during the reign of the Visigoths. The monarch dedicated the construction of a cathedral to the Virgin Mary . Its design is not known, but it is supposedly Romanesque and of the type of contemporary works (of the Abbey of Santo Domingo de Silos, of the Monastery of San Pedro de Arlanza of San Martín de Tours de Frómista or the Cathedral of Jaca). There is documentary evidence that the monarch donated the outdoor area of the royal palace that had belonged to his father Ferdinand I of León and a small church dedicated to Saint Mary that was under construction. In 1096 the construction on this church was finished. But the church soon became too small for the needs of a city that was the symbolic capital of the kingdom, a powerful bishopric (the cathedral chapter had more than thirty canons already before 1200) and an increasingly dynamic business center. The decision to build a new cathedral was finally made in the 13th century. As was common at the time, the Romanesque building was destroyed (of which now only some sculptural elements remain), presumably during the second construction campaign of the new cathedral in the 1240s and the 1250s. And on this site, expanded through the demolition of neighboring houses, with donations by the Bishop Marino, rose a new Gothic cathedral. Floor plan Portico del Sarmental. Transept, South arm.
