The Church of San Esteban de Aramil is of the Romanesque style, popular between the 10th and 13th centuries, but the church itself cannot be dated more exactly. It was first mentioned in documents from 1240 concerning a donation of goods to the monastery of Valdediós by Alvar Diaz and his wife.
There are two theories concerning its origin; one is that it is the last remaining remnant of a monastery and the other is that it is a nobleman's church, which would have served both as the chapel for the castle and the church for the neighboring town.
The church has the classic features of Romanesque architecture; it has a rectangular nave terminated at the southern end by a semicircular apse. Sculptural ornamentation of the church includes the doors, located on the western side of the church and in the apse. The west door has a semicircular arch with two semiarches and screens that rely on separate columns. These columns are formed by shafts supported on bases that have carved lilies forming the columns' capitals, which are decorated with plant motifs. The southern section is less important in addition to being smaller although it is similar in design to the western door. The decor includes protruding sculptured heads, of Norman origin, showing various imaginary animals. There is a small central window in the apse.

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.
