San Babila was once considered the third most important in the city after the Duomo and the Basilica di Sant'Ambrogio. It is dedicated to saint Babylas of Antioch.
At the beginning of the 5th century, Marolus, the bishop of Milan, brought from Antioch to Milan relics of saints Babylas of Antioch and Romanus of Caesarea. Marolus founded the Basilica Concilia Sanctorum or church of San Romano, which stood until the 19th century, a few meters south of the church of San Babila, on the site of a Roman temple dedicated to the Sun.
The church of San Babila was built on the same site in about 1095. In the 16th century, the church was extended with an additional construction at the front and a new baroque façade. The church still retains its original medieval fabric, although much was lost due to baroque and modern renovations.
The whole complex was renovated in the 19th century with the intent of restoring the appearance of the medieval basilica, and in the early 20th century the Neo-Romanesque façade by Paolo Cesa-Bianchi was built. The bell tower is from 1920, and replaced the original tower which fell down in the 16th century.
The interior has a nave and two aisles. There are two side chapels that date from the late Renaissance. The right aisle has an image of the Madonna which is highly venerated by the Milanese population.
References:The Clementinum is a historic complex of buildings in Prague. Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
