Took the train to Lucca in the morning. Lucca is an old city that has retained its medieval city wall. You can walk or bike around the whole old city on top of the wall.
Like all these old cities the streets are narrow, they have old church’s and towers.
After returning to Florence I went to the Duomo and saw the fantastic inside. I also got adventurous and climbed the 463 steps to the top of the dome for and incredible view of Florence.
