Sagrestia Nuova (New Sacristy)

Caterina de' Medici (2 May 1593 – 17 April 1629) was Duchess of Mantua and Montferrat as the second wife of Duke Ferdinando and Governor of Siena from 1627. She was the second daughter of Grand Duke Ferdinando I of Tuscany and his wife Christina of Lorraine.

Anna Maria Luisa de' Medici (11 August 1667 – 18 February 1743) was an Italian noblewoman who was the last lineal descendant of the main branch of the House of Medici. A patron of the arts, she bequeathed the Medicis' large art collection, including the contents of the Uffizi, Palazzo Pitti and the Medicean villas, which she inherited upon her brother Gian Gastone's death in 1737, and her Palatine treasures to the Tuscan state, on the condition that no part of it could be removed from "the Capital of the grand ducal State....[and from] the succession of His Serene Grand Duke."Anna Maria Luisa was the only daughter of Cosimo III de' Medici, Grand Duke of Tuscany, and Marguerite Louise d'Orléans, a niece of Louis XIII of France. On her marriage to Elector Johann Wilhelm II, she became Electress of the Palatinate, and, by patronising musicians, she earned for the contemporary Palatine court the reputation of an important music centre. As Johann Wilhelm had syphilis the union produced no offspring, which, combined with her siblings' barrenness, meant that the Medici were on the verge of extinction. In 1713 Cosimo III altered the Tuscan laws of succession to allow the accession of his daughter, and spent his final years canvassing the European powers to agree to recognise this statute. However, in 1735, as part of a territorial arrangement, the European powers appointed Francis Stephen of Lorraine as heir, and he duly ascended the Tuscan throne in her stead. After the death of Johann Wilhelm, Anna Maria Luisa returned to Florence, where she enjoyed the rank of first lady until the accession of her brother Gian Gastone, who banished her to the Villa La Quiete. When Gian Gastone died in 1737, Francis Stephen's envoy offered Anna Maria Luisa the position of nominal regent of Tuscany, but she declined. Her death, in 1743, brought the grand ducal House of Medici to an end. Her remains were interred in the Medicean necropolis, the Basilica of San Lorenzo, Florence, which she helped complete.

The Medici Chapels (Cappelle medicee) are two structures at the Basilica of San Lorenzo, Florence, Italy, dating from the 16th and 17th centuries, and built as extensions to Brunelleschi's 15th-century church, with the purpose of celebrating the Medici family, patrons of the church and Grand Dukes of Tuscany. The Sagrestia Nuova ("New Sacristy") was designed by Michelangelo. The larger Cappella dei Principi ("Chapel of the Princes"), although proposed in the 16th century, was not begun until the early 17th century, its design being a collaboration between the family and architects. These are not to be confused with the Magi Chapel in the Palazzo Medici Riccardi, then the main Medici home, that houses a famous cycle of frescoes by Benozzo Gozzoli, painted around 1459.

The Basilica di San Lorenzo (Basilica of St. Lawrence) is one of the largest churches of Florence, Italy, situated at the centre of the main market district of the city, and it is the burial place of all the principal members of the Medici family from Cosimo il Vecchio to Cosimo III. It is one of several churches that claim to be the oldest in Florence, having been consecrated in 393 AD, at which time it stood outside the city walls. For three hundred years it was the city's cathedral, before the official seat of the bishop was transferred to Santa Reparata. San Lorenzo was the parish church of the Medici family. In 1419, Giovanni di Bicci de' Medici offered to finance a new church to replace an eleventh-century Romanesque rebuilding. Filippo Brunelleschi, the leading Renaissance architect of the first half of the fifteenth century, was commissioned to design it, but the building, with alterations, was not completed until after his death. The church is part of a larger monastic complex that contains other important architectural and artistic works: the Old Sacristy by Brunelleschi and having interior decoration and sculpture by Donatello; the Laurentian Library by Michelangelo; the New Sacristy based on Michelangelo's designs; and the Medici Chapels by Matteo Nigetti.

The Sagrestia Vecchia di San Lorenzo, or Old Sacristy of San Lorenzo, is the older of two sacristies of the Basilica of San Lorenzo in Florence, Italy. It is one of the most important monuments of the early Italian Renaissance architecture. Designed by Filippo Brunelleschi and paid for by the Medici family, who also used it for their tombs, it set the tone for the development of a new style of architecture that was built around proportion, the unity of elements, and the use of the classical orders. The space came to be called the "Old Sacristy" after a new one was begun in 1510 on the other side of S. Lorenzo's transept.

The Laurentian Library (Biblioteca Medicea Laurenziana or BML) is a historic library in Florence, Italy, containing more than 11,000 manuscripts and 4,500 early printed books. Built in a cloister of the Medicean Basilica di San Lorenzo di Firenze under the patronage of the Medici pope Clement VII, the library was built to emphasize that the Medici were no longer just merchants but members of intelligent and ecclesiastical society. It contains the manuscripts and books belonging to the private library of the Medici family. The library building is renowned for its architecture that was designed by Michelangelo and is an example of Mannerism.All of the book-bound manuscripts in the library are identified in its Codex Laurentianus. The library conserves the Nahuatl Florentine Codex, the Rabula Gospels, the Codex Amiatinus, the Squarcialupi Codex, and the fragmentary Erinna papyrus that contains poems by the putative friend of Sappho.

Cappella dei Principi ("Chapel of the Princes" in English) is the mausoleum of the Grand Dukes of Tuscany and their families and is part of the museum complex of the Medici Chapels of Florence, adjacent to the Basilica di San Lorenzo

Palazzo Della Stufa or Lotteringhi Della Stufa, is in the Piazza San Lorenzo, at the corner of Via della Stufa, in Florence, Italy, in front of the Basilica di San Lorenzo.

The Palazzo or Casa Martelli was a residential palace, and since 2009, a civic museum displaying in situ the remains of the original family's valuable art collection, as well as its frescoed rooms. The palace is located on Via Ferdinando Zannetti 8 near the corner with Via Cerretani in central Florence, region of Tuscany, Italy.

Piazza San Lorenzo is a city square in Florence, Italy, with the Basilica di San Lorenzo situated at the centre.

The Monument to Giovanni delle Bande Nere is an Italian Renaissance sculpture in marble, by Baccio Bandinelli and his workshop, now in Piazza San Lorenzo in Florence, Tuscany, Italy. The work took from 1540 to after 1560 to carve, and the base and statue, though always meant to be together, were only so placed in 1850. The imposing Giovanni sits, somewhat uncomfortably, wearing a metallic cuirass on his torso. Without a helmet or army boots, he holds a baton of command on his knee. The plinth is almost more decorative with festoons and bucranium, and Doric columns at the corners. One bas-relief appears to show soldiers bringing booty and captives before a sitting ruler. Others depict the Medici coat of arms. The corners have doric pilaster-columns.

The Osservatorio Ximeniano is an independent measurement and research building specializing in meteorology and geophysics. It is based in Florence, in a part of the former Collegio degli Scolopi, with access from Piazza San Lorenzo. It is named after Leonardo Ximenes.
