Cathedral of Barcelona

However, its pinnacles and gargoyles contrast with the austerity of the rest of the building.
An image of Christ, surrounded by the Apostles of dominates the main portico. Inside, on both sides of the ship, there is a succession of hoods installed between the buttresses. From the chapel of the souls in purgatory, an elevator leads to the terrace, where some gateways allow the roof of the Church and enjoy splendid views of Barcelona.
