Saint Peter's Basilica is the center of Christianity in Vatican city state. Designed principally by Donato Bramante, Michelangelo, Carlo Maderno and Gian Lorenzo Bernini, St. Peter's is the most renowned work of Renaissance architecture and one of the largest churches in the world. While it is neither the mother church of the Catholic Church nor the cathedral of the Diocese of Rome, St. Peter's is regarded as one of the holiest Catholic shrines.
Catholic tradition holds that the Basilica is the burial site of St. Peter, one of Christ's Apostles and also the first Pope; supposedly, St. Peter's tomb is directly below the high altar of the Basilica. For this reason, many Popes have been interred at St. Peter's since the Early Christian period. There has been a church on this site since the time of the Roman Emperor Constantine the Great. Construction of the present basilica, replacing the Old St. Peter's Basilica of the 4th century AD, began on 18 April 1506 and was completed on 18 November 1626.
St. Peter's is famous as a place of pilgrimage and for its liturgical functions. The Pope presides at a number of liturgies throughout the year, drawing audiences of 15,000 to over 80,000 people, either within the Basilica or the adjoining St. Peter's Square.
St. Peter's has many historical associations, with the Early Christian Church, the Papacy, the Protestant Reformation and Catholic Counter-reformation and numerous artists, especially Michelangelo. As a work of architecture, it is regarded as the greatest building of its age. St. Peter's is one of the four churches in the world that hold the rank of Major Basilica, all four of which are in Rome. Contrary to popular misconception, it is not a cathedral because it is not the seat of a bishop; the Cathedra of the Pope as Bishop of Rome is in the Archbasilica of St. John Lateran.
St. Peter's central dome dominates the skyline of Rome. The basilica is approached via St. Peter's Square, a forecourt in two sections, both surrounded by tall colonnades. The first space is oval and the second trapezoid. The façade of the basilica, with a giant order of columns, stretches across the end of the square and is approached by steps on which stand two 5.55 metres statues of the 1st-century apostles to Rome, Saints Peter and Paul.
The basilica is cruciform in shape, with an elongated nave in the Latin cross form but the early designs were for a centrally planned structure and this is still in evidence in the architecture. The central space is dominated both externally and internally by one of the largest domes (designed by Michelangelo) in the world. The entrance is through a narthex, or entrance hall, which stretches across the building. One of the decorated bronze doors leading from the narthex is the Holy Door, only opened during jubilees.

Le Lude is the most northerly château of the Loire Valley and one of the last important historic castles in France, still inhabited by the same family for the last 260 years. The château is testimony to four centuries of French architecture, as a stronghold transformed into an elegant house during the Renaissance and the 18th century. The monument is located in the valley of Le Loir. Its gardens have evolved throughout the centuries.
