San Giorgio ai Tedeschi

The Leaning Tower of Pisa (Italian: torre pendente di Pisa), or simply, the Tower of Pisa (torre di Pisa [ˈtorre di ˈpiːza; ˈpiːsa]), is the campanile, or freestanding bell tower, of Pisa Cathedral. It is known for its nearly four-degree lean, the result of an unstable foundation. The tower is one of three structures in the Pisa's Cathedral Square (Piazza del Duomo), which includes the cathedral and Pisa Baptistry. The height of the tower is 55.86 metres (183 feet 3 inches) from the ground on the low side and 56.67 m (185 ft 11 in) on the high side. The width of the walls at the base is 2.44 m (8 ft 0 in). Its weight is estimated at 14,500 tonnes (16,000 short tons). The tower has 296 or 294 steps; the seventh floor has two fewer steps on the north-facing staircase. The tower began to lean during construction in the 12th century, due to soft ground which could not properly support the structure's weight. It worsened through the completion of construction in the 14th century. By 1990, the tilt had reached 5.5 degrees. The structure was stabilized by remedial work between 1993 and 2001, which reduced the tilt to 3.97 degrees.

The church of San Ranierino (or Saints Ranieri and Leonardo) is a church located in central Pisa, Italy, near piazza del Duomo.The present building was constructed on this site in the second half of the 19th century. The original church of this name stood adjacent to the hospital facing Piazza dei Miracoli. In 1868, as part of a large urban renewal directed by Luigi Torelli, that structure was demolished and rebuilt at this new site. The church holds an altarpiece depicting Madonna with saints Ranieri, Torpè, and Leonardo by Aurelio Lomi. The marble main altar was completed in the 15th century by Andrea Guardi.

Pisa Cathedral (Italian: Cattedrale Metropolitana Primaziale di Santa Maria Assunta; Duomo di Pisa) is a medieval Roman Catholic cathedral dedicated to the Assumption of the Virgin Mary, in the Piazza dei Miracoli in Pisa, Italy, the oldest of the three structures in the plaza followed by the Pisa Baptistry and the Campanile known as the Leaning Tower of Pisa. The cathedral is a notable example of Romanesque architecture, in particular the style known as Pisan Romanesque. Consecrated in 1118, it is the seat of the Archbishop of Pisa. Construction began in 1063 and was completed in 1092. Additional enlargements and a new facade were built in the 12th century and the roof was replaced after damage from a fire in 1595.

The Orto botanico di Pisa, also known as the Orto Botanico dell'Università di Pisa, is a botanical garden operated by the University of Pisa, and located at via Luca Ghini 5, Pisa, Italy. The garden was established in 1544 under Cosimo I de' Medici as the first university botanical garden in Europe, and entrusted to the famous botanist Luca Ghini of Imola. In 1563 the garden was relocated from its original riverside location (now the Medicean Arsenal) to one near the convent of Santa Marta, and in 1591 (under Joseph Goedenhuyze) again moved to its third and current location. From these early times, the garden has contained a gallery of natural objects (now Pisa's Museo di Storia Naturale), a library (now part of the university library), and portraits of its directors throughout the centuries. It also includes one of the earliest iron-framed hothouses built in Italy. Today the garden is divided into sections containing the botanical school, gardens, ponds, greenhouses, and various buildings. Major collections include herb gardens and arboreta, as well as the old botany institute, built 1591–1595, with a facade ornamented with sea-shells.

The Campo Santo, also known as Camposanto Monumentale ("monumental cemetery") or Camposanto Vecchio ("old cemetery"), is a historical edifice at the northern edge of the Cathedral Square in Pisa, Italy. "Campo Santo" can be literally translated as "holy field", because it is said to have been built around a shipload of sacred soil from Golgotha, brought back to Pisa from the Third Crusade by Ubaldo Lanfranchi, archbishop of Pisa in the 12th century. A legend claims that bodies buried in that ground will rot in just 24 hours. The burial ground lies over the ruins of the old baptistery of the church of Santa Reparata, the church that once stood where the cathedral now stands. The term "monumental" serves to differentiate it from the later-established urban cemetery in Pisa.
