In 1826 Antonín Langweil began to portray the city of Prague in a small model. As a ground plan he used Jüttner's topographical map of Prague, which was published in printed form at the time. During the eleven years of work on the model, Langweil exhibited it five times to the public in unfinished form. In 1833, Langweil was even invited to exhibit the model at an industrial exhibition held in Prague Castle to mark the visit of Emperor and King Francis I to Prague. After the exhibition ended Langweil plucked up the courage to write a letter to the monarch asking for financial support in order to complete work on the model but the request was turned down. Langweil died in June 1837 at the age of 46 and left the model unfinished.
