This gallery contains projects prepared at the behest of the Medici Grand Dukes for a modern front for the Cathedral: seven large wood models illustrating proposals for a Renaissance façade in place of the medieval one demolished in 1587. The reconstructed original façade, visible through high windows in the gallery wall, invites visitors to measure the distance between the style of the Middle Ages and that of architects of the Mannerist and early Baroque periods. This galley also contains two paintings made in 1589 for the wedding of Grand Duke Ferdinand I to the French princess Christine of Lorraine, along with copies of three of the colossal statues realised for the ephemeral façade that adorned the Duomo on that occasion. The original statues are in the north-west tribune of the Cathedral, on the route leading to the top of the dome.
The ticket allows the holder to visit all the monuments within 72 hours of visiting the first one. Each monument may be visited only once with the ticket.
Reservations mandatory for the climb on the Dome. The service is free.
