“Forming part of the monumental San Lorenzo complex (the Medicis' parish church, worth seeing but largely ignored by tourists), the Cappelle Medicee were Michelangelo's first architectural projects, begun in the 1520s and designed to hold the remains of Lorenzo the Magnificent and three other members of the ruling clan. The chapels are famous for the reclining, allegorical statues of female Dawn and male Dusk that adorn the tomb of Lorenzo II, Duke of Urbino (grandson of Lorenzo II Magnifico), and for the figures of male Day and female Night on the tomb of Giuliano, Duke of Memours. Ironically, Michelangelo didn't complete the two most important tombs--those of Lorenzo Il Magnifico and his brother, Giuliano, who lie in a plain tomb opposite the altar. Later (and lesser) tombs hold the remains of the Medici monarchs who ruled till the end of the line in 1737.
