Ulm Minster, like Cologne Cathedral, was begun in the Gothic era and not completed until the late 19th century. It is the tallest church in the world, and the 4th tallest structure built before the 20th century, with a steeple measuring 161.5 metres. From the top level at 143m there is a panoramic view of Ulm.
The foundation stone was laid in 1377. The planned church was to have three naves of equal height, a main spire on the west and two steeples above the choir. In 1392 Ulrich Ensingen (associated with Strasbourg Cathedral) was appointed master builder. It was his plan to make the western church tower the tallest spire, which it remains in the present day. The church, consisting of the longitudinal naves and the choir, covered by a temporary roof, was consecrated in 1405. However, structural damage, caused by the height of the naves and the weight of the heavy vaulting, necessitated a reconstruction of the lateral naves which were supported by a row of additional column in their centre.
In a referendum in 1530/31, the citizens of Ulm converted to Protestantism during the Reformation. Ulm Minster became a Lutheran church. In 1543 construction work was halted at a time when the steeple had reached a height of some 100 metres. The halt in the building process was caused by a variety of factors which were political and religious as well as economic. One result was economic stagnation and a steady decline, preventing major public expenditure.
In 1817 work resumed and the three steeples of the church were completed. Finally, on 31 May 1890 the building was completed.
A devastating air raid hit Ulm on 17 December 1944, which destroyed virtually the entire town west of the church to the railway station and north of the church up to the outskirts. The church itself was barely damaged. However, almost all the other buildings of the town square (Münsterplatz) were severely hit and some 80% of the medieval centre of Ulm was destroyed.

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.
