Seville's Cathedral, with two aisles plus chapels on each side of the nave, is the world's largest Gothic building. There's room for a ball game and a church service at the same time, neither would disturb the other. Its bell tower, The Giralda, is one of the finest examples of Moorish tower architecture. The Cathedral is huge, and a portion of the ceiling vaults are embellished by barnacle-like encrustation. There are 45 yard-square sculptured scenes, each filled with intense detail.
The City of Seville and its Cathedral are fascinating and attractive, and certainly deserved much more time than we had available, that time.
