Of all the towers built today, eight are bell towers on the Nativity and Passion
façades, four each. With the four bell towers to be built on the Glory façade,
there will be twelve in total. These towers, which stand between 98.5 and
120 metres tall, represent the apostles.So, each one bears the name of an
apostle and his image sculpted in a seated position. For the same reason,
each one is crowned with a pinnacle that symbolically represents the attributes of
the bishops, the successors of the apostles: the mitre with the cross, the crosier and
the ring, done in trencadís mosaic with coloured Venetian glass.
The bell towers on the Nativity façade are dedicated to the apostles Barnabas,
Simon, Jude Thaddeus and Matthias.The first was finished in 1925 and the
other three, in 1930. The bell towerson the Passion façade, which were
completed in 1977, are dedicated to James the Less, Bartholomew, Thomas and Philip.
