The Cathedral of Our Lady of the Holy Assumption in Valladolid was originally designed as the largest cathedral in Europe. Initially planned as the Cathedral for the capital city of Spain, ultimately, only 40-45% of the intended project was completed, due to lack of resources after the court moved towards Madrid, and the expenses caused by the difficult foundations of the church.
The structure has its origins in a late Gothic collegiate church, which begun in the late 15th century. The cathedral that was planned would have been immense. When construction started, Valladolid was the de facto capital of Spain, housing king Philip II and his court. However, due to strategic and geopolitical reasons, by the 1560s the capital was moved to Madrid and construction funds were largely cut. Thus the cathedral was not finished according to Herrera's design, and further modified during the 17th and 18th centuries, such as the addition to the top of the main façade, a work by Churriguera.
Its main façade is made up of two stretches of columns: the lower part, the work of Juan de Herrera, and the upper, that of Churriguera, which is characterised by its abundant decorative elements. The inside of the building is split up into three naves with side chapels between the butresses. The 15th century altarpiece is the work of Juan de Juni and depicts figures of saints. The Cathedral Museum is also to be found inside the church.
References:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
