NTK's Motto

"The library is a service"


Founding and Early History


The National Library of Technology in Prague originated in 1718 as a donation of a collection of books that once belonged to Christian Willenberg (1655-1731), the first Engineering Professor of the Czech Estates.

On November 9, 1717, the Czech Estates Decree instituted the "Professorship of Engineering" for the purpose of teaching "military skills" (i.e., construction of fortifications). Effective January 1, 1718, Professor Willenberg was given 300 gold coins to purchase books and teaching materials, which were used to start the library's historical collection.

Initially, the library materials were stored in Willenberg's apartment in the so-called Saxon House located in Prague's Lesser Town, where he also taught courses. The decree also appointed 12 individuals to serve as his students. 


In 1720, students' complaints about the inconvenience of having to walk from their dormitories in Old Town across Charles Bridge to Willenberg's apartment prompted him to move. The book collection was then transferred to a house on the corner of Liliová and Anenská Streets (identified as a hostel for tailor's journeymen) in Prague's Old Town.

On March 1, 1726, Johan Ferdinand Schor (1686-1767) was appointed as the second Engineering Professor of the Estates. Professor Schor taught students from his apartment in the Golden Wreath House on Small Square, where he curated the materials and used his own funds to enrich the collection.

Professor Herget


Beginning in 1767, student enrollment at the Estates School of Engineering (the original name given to the Engineering Professorship of the Estates) significantly increased under the director of Franz Leonhard Herget (1741-1800). Continuing the tradition of teaching students and managing the library, Herget's first location was at Týnská Street, in the so-called Broumovský House on Kozí Plácek Square, that was demolished in 1900.  Later, he taught in a house at the corner of Old Town Square and Melantrichova Street.


The need for more space prompted Herget to relocate the engineering school to the Clementinum (1777-1786). The new site included a lecture room, three small rooms for library materials, and a garden with a water drive that allowed for the performance of mechanical and physical experiments. While the exact location within Clementinum remains unknown, it is assumed to have been somewhere in the southern wing in a former Jesuit print shop (now the Karlova Street entrance).

In 1778, the Estates began paying Professor Herget an annual allotment of 250 goldens to purchase library materials.  During this time, the school's shifting interests from military to civil engineering was reflective of Herget's library collection policy that began adding resources in mathematics, physics, architecture, and mechanics.


In 1786, one of Herget's most significant achievements was the acquisition of St Wenceslas' Seminary, a former Jesuit seminary, for the engineering school. The Old Town building currently remains on Husova Street (formerly Dominikánská Street).

St Wenceslas' Seminary

The polytechnic educational institutes (predecessors of present-day Czech Technical University between 1786-1935) were formed under the roof of the former St Wenceslas' Seminary.

In 1806, the Estates School of Engineering officially transitioned into the Estates Polytechnic Institute. In 1869, the Institute became separated into two entities-Czech and German Institutes. In 1875, both sites were managed by the Austrian Ministry of Culture (previously, they were governed by the Czech self-administration authorities).  The library served students and scholars from both Institutes until 1945, when the German Institute was closed.  Until 1960, the library's official name was the Technical Universities Library.

The library was located in the rear section of the seminary. In 1834, a two-story wing was erected in the seminary's courtyard, which meant that visitors had to walk across two courtyards in order to gain entry from the street. Originally, the first floor of library consisted of three rooms with a total floor area of 114 m2. In 1875, a renovated flat that had previously belonged to the Institute's Director, created a student reading room, gave the library 73 more seats, and an additional 102 m2 (beginning in 1863, the Institute no longer had a Director but rather a Rector an elected position appointed to a one-year term). In the effort to keep apace with the collection's continued growth, in 1891 the German Institute's Rector assigned another hall to its operations. 

During the early 1830s the collection was managed by notable librarian František Josef Knight Gerstner (1756-1832), who began the systematic classification of materials. On May 31, 1831, Gerstner entrusted Karl Joseph Napoleon Balling (1805-1868), an adjunct in the chemistry department and later professor and rector of the Institute, with the task of organizing books previously acquired by other professors. Establishing five thematic groups for organization of the library's materials: mathematics, architecture, chemistry, mechanical, and military engineering, Balling served as library director until 1865.

Technical Universities Library (TUL) in East Wing of the Clementinum


In 1920, during the inagural meeting of the university council of the newly established German/Czech Technical University, a decison was made "to move the shared technical library into more appropriate spaces." In February 1927, the Rectors of the German and Czech Technical Universities jointly appealed to the Ministry of Education to create a common Technical Universities Library (TUL) in the Clementinum. In response to the petition Dr. Borecký, the director of the public and university library,  assigned part of the eastern wing of the Clementinum to the TUL.

In early 1931, the Ministry of Finance approved renovation for the library, with secondary approval from the Ministry of Public Works in June 1932. The budget drafted by the Ministry of Public Works was 4.4 million CZK, with an additional 25,000 CZK designated for historic preservation of the large reading room's ceiling.

Working in conjunction with library director PhDr. Antonín Moucha, the renovations were completed by Architec Dr. Ing. Ladislav Machoň and the library was opened on May 9, 1935. The reading room accommodated 142 readers and the historical wooden ceiling (previously the Jesuit theatre) was renovated by Academy of Arts graduate B. Číla. Praised across Central Europe for its technical innovations, the library's interior featured a pneumatic mail system, which consisted horizontal and vertical tubes that allowed for transport of one-three publications in closed metal baskets. The system was based on an original design by Dr. Moucha and was manufactured specially for the library by Mikrofone. These renovations increased vistorship from 37,000 patrons in 1934 to over 100,000 by 1936.

State Library of Technology

In 1960, the library was renamed as the State Library of Technology (STK). Having now outgrown the space at the Clementinum, the library procured remote storage facilities over four years, beginning in 1974, in Prague 4-Písnice and in Lhota near Dolní Břežany (each with capacity for 200,000 volumes). Despite the additional storage facilities, space for the library's collection remained inadequate. By the mid-1990s, the Ministry approved contruction of a new National Library of Technology in Prague 6-Dejvice, on Prague's engineering campus.

National Library of Technology

Construction of the National Library of Technology (NTK) began in 2006. The modern, state of the art building opened in September 2009. An aesthetically pleasing place to broaden both the mind and the spirit, the library was designed to hold more than 1.7 million volumes and there are up to 500,000 volumes accessible in open stacks. The building includes 1,286 study spaces, 29 individual study carrels, 18 team study rooms, a 24-hour After Hours Study Room, a cafe, a gallery, bookstore, and 448 places to relax.
