The city of Bath was first founded by the Celts under the name of Sulis in the valley of the Avon River, around its natural hot springs. The Celts believed this area to be sacred. After the Roman conquista of AD 43, the site's name was changed to Aqua Sulis, when the Romans built temples and baths here. Today, the Roman baths are the city's major attraction. Bath was declared a city by Queen Elisabeth I in 1590. Through the centuries, the town managed to preserve the history of generations and cultures. The charm of the hot springs and its sacred enigma are perhaps among factors which preserved the site almost completely intact, seen in the architecture, ruins and museums. The city has been inspiration for artists and great minds for centuries. Jane Austin lived here in the beginning of the 19th Century. Annual festivals are also held in Bath, including the Bath International Music Festival, the Mozartfest and the Bath Film Festival. The Bath Spa attracts many tourists to the natural energy and beauty of the hot springs.
