Perugia, capital of Umbria, with its medieval alleyways, breathtaking views and typical dishes, has a lot to offer visitors. Piazza IV Novembre, located in Perugia's historic centre, , built in 1345 and dedicated to one of the city's patrons, is one of the city's most beautiful squares . The square is also home to the most important places of worship, the San Lorenzo Cathedral, whose entrance is located in Piazza Dante. The Maggiore fountain stands in the centre of the square and is the true symbol of the city, built between 1275 and 1278 by Nicola and Giovanni Pisano. Its decorations exude an iconic language which reflects the political and cultural programme of the Municipality of Perugia. The Etruscan Well is an important work of hydraulic engineering located next to the Maggiore Fountain, in Piazza Danti, built in the latter half of the third century BC and 37 metres deep.
