Cathedral

Jaca's most important building is the Romanesque Cathedral, which in later Centuries was altered and given Plateresque decoration.
The square tower, the outer walls, the main doorway and the south doorway are all Romanesque.

Typical characteristics of Romanesque architecture include thick stone walls, perfectly semicircular arches, barrel vaults, carved portals and little but predominantly geometric decoration (checkers, zig-zags, etc.). In addition, due to the insecurity of Romanesque architects about the best way to construct, doorways and windows are generally extremely narrow; interiors tend to be dim and solemn due to the lack of natural light.

There is very fine figural decoration on the south doorway and its porch: the capitals are very beautiful with a lot of representations of Bible stories.
In the choir and the dome of the central apse are frescoes by Bayeu.
In the cloister of the Jaca Cathedral is the Diocesan Museum, which in addition to a variety of religious objects displays a magnificent collection of Romanesque wall paintings from churches in the Aragonese Pyrenees.

In conclusion, if you are a lover of the Romanesque style, you have to visit Jaca, the Saint Peter's Cathedral to admire one of the most ancient cathedrals in Spain. You can also visit smaller Romanesque churches in the surrounding villages like Santa Cruz de la Serós and San Juan de la Peña.
