San Lorenzo Basilica Florence is part of the Opera Medicea Laurenziana, which was established in 1907 to honor the Medici Laurentian Complex. It is composed of the basilica of San Lorenzo, the Old Sacristy, the cloisters, the Medicea Laurenziana Library and the Museum of the Medici Chapels.
A large Basilica near the Duomo. Brunelleschi, Manetti, Donatello and Michelangelo all had a hand in designing it. Most of the Medici are buried here. The facade is barren and bleak, awaiting Michelangelo who received the commission but never finished it. It is interesting inside of course. The cobbles outside are pretty horrible bone-shakers but Catholicism is all about suffering after all. There is a famous Medici chapel at the back (outside) of the basilica but I am pretty sure it is inaccessible for wheelies.
Access was via a ramp at the front when I visited in 2011. I recall they had to get a crusty portable wooden ramp and I also had to use my trusty portable ramp. In 2015 a new ramp was built on the North side (Piazza di San Lorenzo) overlooking the outdoor market. Those Italians love to get us wheelies into church.
