Spain - Seville - Cathedral Interior
From Wikipedia : 'The city's cathedral was built from 1401–1519 after the Reconquista on the former site of the city's mosque. It is amongst the largest of all medieval and Gothic cathedrals, in terms of both area and volume. The interior is the longest nave in Spain, and is lavishly decorated, with a large quantity of gold evident. The Cathedral reused some columns and elements from the mosque, and, most famously, the Giralda, originally a minaret, was converted into a bell tower. It is topped with a statue, known locally as El Giraldillo, representing Faith. The tower's interior was built with ramps rather than stairs, to allow the Muezzin and others to ride on horseback to the top.'
