The Basilica of Corpus Domini was built to celebrate the 'Miracle of the Eucharist' which, according to various sources, occurred in 1453 during the war between the Duchy of Savoy and France.
The event which led to the construction of the church occurred on 6 June 1453 during the war between Louis of Savoy and France. A group of French soldiers had plundered the main church in Exilles, a town in the Val di Susa. On 6 June, the day of the Feast of Corpus Christi, they went to Turin to sell the booty. The donkey which transported the sacramental bread from the Exilles' church fell on the ground and the Holy Spirit rose and illuminated the square from the air.
To celebrate the event, the painting of the Holy Name of Jesus was painted on the four gates of the city but this was deemed insufficient, and in 1509 a small chapel was soon commissioned on the present church's site. However, nothing was built until 1521, when Innocenzo Cybo, Archbishop of Turin, ordered the construction of a small oratory by Matteo Sanmicheli. This was demolished in 1607 to make room to the modern basilica.
The design of the new church was commissioned to Ascanio Vitozzi. Amedeo di Castellamonte collaborated in the designing of the façade. Works began in 1607. In 1753 king Charles Emmanuel III of Savoy commissioned Benedetto Alfieri to restore the interior decoration and to ornament it with stuccoes.
The church has a massive façade, with six pilasters and four columns supporting the entablature, in typical Baroque style. It is completed by statue of angels and saints by Bernardo Falconi, dating to the late 17th century.
The interior has a single nave, and was largely renewed in the 18th century. The high altar is the original one, created by Francesco Lanfranchi in 1664. The interior also houses a slab marking the exact place of the miracle.
References:Rosenborg Palace was built in the period 1606-34 as Christian IV’s summerhouse just outside the ramparts of Copenhagen. Christian IV was very fond of the palace and often stayed at the castle when he resided in Copenhagen, and it was here that he died in 1648. After his death, the palace passed to his son King Frederik III, who together with his queen, Sophie Amalie, carried out several types of modernisation.
The last king who used the place as a residence was Frederik IV, and around 1720, Rosenborg was abandoned in favor of Frederiksborg Palace.Through the 1700s, considerable art treasures were collected at Rosenborg Castle, among other things items from the estates of deceased royalty and from Christiansborg after the fire there in 1794.
Soon the idea of a museum arose, and that was realised in 1833, which is The Royal Danish Collection’s official year of establishment.
