Jelaskan Interior dari Katedral Santiago de Compostela dalam bahasa melayu

The cathedral is 97 m long and 22 m high. It preserves its original barrel-vaulted cruciform Romanesque interior. It consists of a nave, two lateral aisles,  a wide transept and a choir with radiating chapels. Compared with many other important churches, the interior of this cathedral gives a first impression of austerity until one enters further and sees the magnificent organ and the exuberance of the choir. This cathedral, through its monumental dimensions, is the largest Romanesque church in Spain and even one of the largest in Europe.
