On the way back to the hotel, we passed the Duomo which has to be one of the most beautiful churches ever. The cathedral was begun in 1296 and the interior is quite austere. It was completed in 1436 with the magnificent Brunelleschi dome and was renovatd in the 19th century with a Gothic Revival facade. It never fails to impress. Along with the bell tower and the baptistry, the square is unforgettable.
