The collegiate church of Santa María la Mayor Monument · Briviesca, La Bureba, Burgos The former collegiate church of Santa María la Mayor of Briviesca, today reduced to the rank of parish church and closed to worship, was founded in the second decade of the 14th century by the infanta Blanche of Portugal, lady of the Monastery of Santa María la Real de las Huelgas and daughter of King Afonso III of Portugal, and was the first of the five collegiate churches of the diocese of Burgos. The building, an amalgam of styles in which the baroque and the neoclassical predominate today, was rebuilt between 1789 and 1794 with the surviving neoclassical facade of twin towers topped by a dome, designed by Manuel Echanove. Declared a Bien de Interés Cultural (Spain's highest level of heritage protection) with the rank of national historic-artistic monument in 1982, it is one of the oldest collegiate churches in Spain.
