Gaudì had planned 18 towers for the Cathedral but only 8 has been completed for now: 4 on the Nativity facade and 4 on the Passion facade.
The admission to the towers is not included in the base fare. They can be purchased as an extra. Because of the few tickets available, it is recommended to buy them well in advance.
There is a lift for each facade and it is the only way to reach the top of the towers. Choose the Nativity facade to have a sight on the east of the city or the Passion facade to admire the West landscape.
The lift is used to go down from the Passion tower while for the Nativity tower you need to take the stairs.
For security reasons, children under the age of 6 cannot climb the towers and children under the age of 16 must be accompanied by an adult. The towers' lift could be closed in case of heavy rains or wind.
