The oldest part of Lovö Church has been dated back to the later part of the 12th century. According Berit Wallenberg it was built as early as the 11th century. It is also believed that an even older wooden church existed on this site. Church sermons are held in the church, normally once a month, and for certain Christian holidays.
The church is unusually small and narrow. It was extended to the east, first in the 13th and further in the 17th century. Churches built during this time were built with a weapons room, a foyer where people going to church had to lay down their arms before entering the church itself. This weapons house was demolished in 1798, and an entry was made in the west side of the attached church tower. There are also five Viking Age memorial runestones that are located outside the Lovö church.
The sanctuary of the church was created around 1670. The architect is believed to be Nicodemus Tessin the Elder, who was working on Drottningholm Palace around this same time. Inside the church are 30 gravestones, several of which belonged to people employed at Drottningholm palace. The interior was renovated in 2004.

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.
