Florence’s centre is home to outstanding historical treasures, which is why, in 1982, UNESCO declared the area a World Heritage Site. It’s not hard to agree with that decision: a visit to piazza Duomo and you’ll be treated to incredible traces of the Renaissance, like the Cathedral of Santa Maria del Fiore - built in a typically Italian Gothic style - and Giotto’s famed bell tower. The cathedral’s imposing dome, built by Brunelleschi, remains an outstanding example of architectural genius.
