The stone church of Adelsö was built in the late 1100s. No traces have been found of the first church on the location, but it is assumed it was made of wood. This original structure was however replaced by a stone building, possibly initiated by the king living at the royal estate at Hovgården. If true, the church thus originally served both the local parish and the royal mansion.
The stone structure originally had a nave furnished with a narrow choir which possibly ended in an apse. The sacristy was added in the 14th century, and during the century that followed the tower and then the brick vaults were added. In the 1470s, the choir was widened and united with the nave. The exterior of the tower was created in 1753. and finally, 70 years later, the entrance was relocated from the southern façade to the western end; old windows were enlarged and new windows were added.
There is a baptismal font which dates from the 12th century and a crucifix from the later half of the 14th century. The pulpit dates from 1786 and the gallery from 1832. The votive ship hanging in the church was donated in 1960.
Two Viking Age memorial runestones are built into the walls of the sacristy, one designated in the Rundata catalog as Uppland Runic Inscription 1or U 1 and the other as Uppland Runic Inscription 10 or U 10. Additionally, the so called Hovgården Runestone, U 11, is located just north of the church, near the ruins of the medieval brick palace Alsnö hus.

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.
