The proportions of the building are however not lost and its scale and grandeur remain just as imposing as you stand in front of the main portico. This portico has aesthetic and historic importance. As a piece of architecture and masonry it is incredibly detailed and one awes at the thousands of man hours that must have gone into its making, but it also represents the first instance of Gothic art in Spain. Other elements of the building are also Gothic, but the oldest sections and main architectural styling are Romanesque.
