The Colosseum ( KOL-?-SEE-?m), also known as the Flavian Amphitheatre (Latin: Amphitheatrum Flavium; Italian: Anfiteatro Flavio [a?fite?a?tro ?fla?vjo] or Colosseo [kolos?s??o]), is an oval amphitheatre in the middle of the city of Rome, Italy. Constructed of travertine limestone, tuff (volcanic rock), and brick-faced concrete, it was the largest amphitheatre ever constructed at the time and held 50,000 to 80,000 spectators. The Colosseum is just east of the Roman Forum. Construction started under the emperor Vespasian in AD 72 and was completed in AD 80 beneath his successor and heir, Titus. Further modifications were made during the reign of Domitian (81--96). These three emperors are known as the Flavian dynasty, and the amphitheatre was named in Latin because of its association with their family name (Flavius).
The Colosseum could hold an estimated 50,000 to 80,000 spectators at various points of its history over the centuries, having a typical audience of some 65,000; it was used for gladiatorial contests and public spectacles such as mock sea battles (for only a short time as the hypogeum was soon filled in with mechanisms to support the other activities), animal hunts, executions, re-enactments of famous battles, and dramas based on mythology.

City | Pisa |
The Leaning Tower of Pisa (Italian: Torre pendente di Pisa) or simply the Tower of Pisa (Torre di Pisa [?torre di ?pi?za]) is the campanile, or freestanding bell tower, of the cathedral of this Italian city of Pisa, known globally for its almost four-degree lean, the result of an unstable foundation. The tower is situated behind the Pisa Cathedral and is the third-oldest structure in the city's Cathedral Square (Piazza del Duomo), following the palace and the Pisa Baptistry. The height of this tower is 55.86 metres (183.27 feet) from the ground on the low side and 56.67 metres (185.93 feet) on the high side. The width of the walls at the base is 2.44 m (8 feet 0.06 in). Its weight is estimated at 14,500 metric tons (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, and it worsened through the completion of building 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 decreased the tilt to 3.97 degrees.
