Sevilla Cathedral is known for being the biggest Gothic Cathedral of the world, also world’s third biggest cathedral, home of Cristopher Colombus’ tomb. The Cathedral along with the Alcazar and the General Archive of Indies are cited as Unesco sites. The Cathedral was constructed on the site of the Almohad Mosque dating from eleventh century and lasted more than hundred years. One can see the remains of the mosque like the fountain and the patio with orange trees; the tower, Giralda, is also inspired from the minaret of the Koutoubia Mosque in Marrakesh. The decision of building a Cathedral by Ferdinand the 3rd (his tomb is also inside the cathedral) was aiming to show the world the huge fortune made by being an important port city as it can be seen in all the gold and silver work used in the cathedral (especially in the chorus). As the story tells ‘let’s make something that would make the world think we are crazy’ was somewhat a grotesque way of showing the richness of Sevilla at that time. Inside the cathedral one cannot stop but admire the architecture, the columns carrying the longest nave the cathedral has in Spain, the box choir with figures of Christian personalities, each lighted separately to attract the viewer, the Giralda Tower which you can climb through 34 inclines where you stop and watch the outer walls of the cathedral from its windows. The tomb of Colombus is carried on four soldier sculptures. Outside the cathedral the doors merit attention. You can then go into the streets of the old town of Seville.
