The Church of Our Lady of... by Ronald_T
The Church of Our Lady of Guanajuato became the Basilica in 1957. Its façade is mannerist-baroque in style. Within the church, you can see a sculpture of the Virgin of Guanajuato, the city?s patron and a gift from King Carlos V of Spain and his son, Felipe II, in 1957. It was also the year of my birth ;-)
For more info and pictures, look in my Church of Our Lady travelogue please?
