Church of St. Gertrude (Šv. Gertrūdos bažnyčia) is one of the oldest Brick Gothic churches in Lithuania. The exact date when the church was built is unknown, but it must have been in the 15th century. In 1503 Grand Duke of Lithuania Alexander designated the church as a parish church of Kaunas. In the middle of the 16th century a bell tower was attached. The church was damaged in 1655 during the Russo-Polish War (1654–1667). It was rebuilt only around 1680. Around 1750 a wooden hospital was attached to the church. In 1782 it was abandoned for a long time, and at the time there were 5 monks from order of St. Roch residing. In 1796 the church was renovated, organs installed, and living quarters for aparson established. The church was consecrated in 1794.
In 1812 Kaunas suffered from a major fire, which also damaged the church. The hospital was abandoned, and in 1824 transferred to the sister order of Caritas. The monastery was closed in 1864 after the January Uprising. The old hospital was demolished in 1880. In 1921 the church was assigned to the Marianites of Holy Cross and a monastery was built nearby. In 1920 the church was daubed. In 1992 a complex renovation of the church and monastery took place. Since 1991 the Mass is held in the church again, and the Marianites monastery has been returned to the monks.

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.
