Museum Medici Chapel in Florence

You're standing at the back of San Lorenzo, the parish church of the Medici family. Take a look up at that huge dome. It's 59 metres high and sits on an eight-sided chapel. From far across the city, this dome is how you spot San Lorenzo. Underneath it are the Medici Chapels, built as an extension of the church with one clear purpose: to glorify the Medici, the Grand Dukes of Tuscany.
