Rainfall average.Cardiff - the city is relatively small, so tourists can easily spend seeing the sights, just traveling on foot or by renting a bicycle. To truly understand the spirit of this ancient city with a thousand years of history have to visit a lot of sites.Cardiff castle Cardiff Castle is situated on the site of the ruins of the Roman Church. His story is impressive: the first wall of the building was carried out of the fort functions, then he became the court, and after - the seat of nobility. The beautiful Victorian mansion castle was only during the reign of the Marquis of Bute. The owner completely rebuilt the castle in its grounds, and say that he had excellent taste - it does not say anything.
