Saint Peter's Basilica in the context of "Pope Nicholas V"

The Catholic Church in Europe is part of the worldwide Catholic Church in full communion with the Holy See in Rome, including represented Eastern Catholic missions. Demographically, Catholics are the largest religious group in Europe.

The Pietà (Madonna della Pietà, Italian: [maˈdɔnna della pjeˈta]; '[Our Lady of] Pity'; 1498–1499) is a Carrara marble sculpture of Jesus and Mary at Mount Golgotha representing the "Sixth Sorrow" of the Virgin Mary by Michelangelo Buonarroti, in Saint Peter's Basilica, Vatican City, for which it was made. It is a key work of Italian Renaissance sculpture and often taken as the start of the High Renaissance.

The sculpture captures the moment when Jesus, taken down from the cross, is given to his mother Mary. Mary looks younger than Jesus; art historians believe Michelangelo was inspired by a passage in Dante Alighieri's Divine Comedy: "O virgin mother, daughter of your Son [...] your merit so ennobled human nature that its divine Creator did not hesitate to become its creature" (Paradiso, Canto XXXIII). Michelangelo's aesthetic interpretation of the Pietà is unprecedented in Italian sculpture because it balances early forms of naturalism with the Renaissance ideals of classical beauty.

The Vatican Necropolis is a necropolis that lies underneath Vatican City containing tombs dating from the first to fourth century AD, at depths varying between 5 and 12 metres (16 and 39 ft) below Saint Peter's Basilica. The Vatican sponsored archaeological excavations (also known by their Italian name scavi) under Saint Peter's in the years 1940–1949, which revealed parts of a necropolis dating to the Roman Empire. It is the home to the Tomb of the Julii, which has been dated to the third or fourth century. The necropolis was not originally one of the Catacombs of Rome, but an open-air cemetery with tombs and mausolea.

The Vatican Necropolis is not to be confused with the Vatican Grottoes, the latter of which resulted from the construction of St. Peter's Church and is located on the ground level of the old Constantinian basilica.

Redemptoris Mater (Latin: Mother of the Redeemer) is an encyclical by Pope John Paul II delivered on March 25, 1987 in Saint Peter's Basilica in Rome. Subtitled On the Blessed Virgin Mary in the life of the Pilgrim Church, the text addresses a number of topics in Mariology.

The Basilica of Our Lady of Peace (French: Basilique Notre-Dame de la Paix, pronounced [bazilik nɔtʁə dam də la pɛ]) is a Catholic minor basilica dedicated to Our Lady of Peace in Yamoussoukro, the administrative capital of Côte d'Ivoire (Ivory Coast). Guinness World Records lists it as the largest church in the world, having surpassed the previous record holder, Saint Peter's Basilica, upon completion. It has an area of 30,000 square metres (320,000 sq ft) and is 158 metres (518 ft) tall. However, it also includes a rectory and a villa (counted in the overall area), which are not strictly part of the church. It can accommodate 18,000 worshippers, compared to 60,000 for St. Peter's. Ordinary liturgies conducted at the basilica are usually attended by only a few hundred people. The basilica is administered by Polish Pallottines at a cost of US$1.5 million annually.

The basilica was constructed between 1985 and 1989 with different cost estimates given by various groups. Some stated that it cost US$175 million, US$300 million, or as high as US$600 million. The designs of the dome and encircled plaza are clearly inspired by the Basilica of Saint Peter in Vatican City, although it is not an outright replica. The cornerstone was laid on 10 August 1985, and it was consecrated on 10 September 1990 by Pope John Paul II, who had just formally accepted the basilica as a gift from Félix Houphouët-Boigny on behalf of the Catholic Church.

The Pietà (Italian pronunciation: [pjeˈta]; meaning "pity", "compassion") is a subject in Christian art depicting the Blessed Virgin Mary cradling the mortal body of Jesus Christ after his Descent from the Cross. It is most often found in sculpture. The Pietà is a specific form of the Lamentation of Christ in which Jesus is mourned by the Virgin Mary alone. However, in practice works called a Pietà may include angels, the other figures usual in Lamentations, and even donor portraits.

An image consisting only of a dead Christ with angels is also called a Pietà, at least in German, where Engelpietà (literally "Angel Pietà") is the term for what is usually called Dead Christ supported by angels in English.
