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:The ancient Argos Theater was built in 320 BC. and is located in Argos, Greece against Larissa Hill. Nearby from this site is Agora, Roman Odeon, and the Baths of Argos. The theater is one of the largest architectural developments in Greece and was renovated in ca 120 AD.
The Hellenistic theater at Argos is cut into the hillside of the Larisa, with 90 steps up a steep incline, forming a narrow rectilinear cavea. Among the largest theaters in Greece, it held about 20,000 spectators and is divided by two landings into three horizontal sections. Staircases further divide the cavea into four cunei, corresponding to the tribes of Argos A high wall was erected to prevent unauthorized access into the theatron and may have helped the acoustics, but it is said the sound quality is still very good today.
Around 120 CE, both theaters were renovated in the Roman style.
