Start with “The Duomo and the Baptistery”. You start where Dante was baptised and walk round the Baptistery: the carpenter who, according to a novella of the time, was talked into believing he was another man; the elm that, tradition says, flowered in January; and the 1401 contest that every contender told his own way. Then the confraternity that has been carrying the sick for eight centuries, and its hooded men in black; a façade tried out at full size in front of the public; Brunelleschi's egg; the stone where tradition sits Dante; and the marble disc that, they say, marks where the ball from the lantern fell.
Then there’s “Via de' Bardi and San Niccolò”. You start where the street was once called "Lousy", before it came to belong to the Bardi, bankers who lent money to a king of England and were never paid back. Beside the Uzzano palace you'll hear why one man refused to bring down Cosimo de' Medici, and in front of a marble plaque of 1565, how a boy was pulled alive from the rubble and grew up to be an architect at court.
For another side of the city, try “Dante's Florence”. Within a hundred metres of narrow streets lived the Portinari, the Donati, the Cerchi and the Alighieri. You start in front of the palazzo that, according to a nineteenth-century identification, contains the houses of the Portinari, Beatrice's family, and which also has a legend about a little boy and a window.
