The oldest plan available on the geoportal dates back to the 18th century.

Plans from the 18th and early 19th centuries are characterized by higher accuracy, which was required, for example, in the vicinity of the fortifications of Prague. The first plan created on a geodetic basis was Jüttner's plan of Prague.

Herget's plan of Prague 1791

The first accurately measured plan of the historical cities of Prague (and Smíchov) was completed in 1791 by mathematician, engineer and professor of the Estates Engineering School František Antonín Leonard Herget (1741-1800).

At a 1 : 1,728 scale plan the houses are already marked with numbers according to the so-called first numbering from 1770 (Prague houses were renumbered again in 1805). Important buildings with gardens are those predominantly depicted in detail. The quality of the focus and the accuracy of the drawing of details is variable; inaccuracy is higher in the peripheral parts and near the fortifications. The significantly spatially deformed plan was rectified for display in the application over the base of the original map of the stable cadastre (1842).

The plan is stored in the Archives of Prague, sign. MAP P 1 B/1.

Jüttner's plan of Prague 1816

Josef Jüttner (1775 - 1848) was an artillery officer in the Austrian army and the creator of the first plan of Prague based on geodetic data. In 1803 he was a participant in the astronomical determination of the coordinates of the observatory at Hradčany and the measurement of the base at Letná. He used it to create the trigonometric network of Prague in 1811.

In February 1812, Emperor Francis I ordered the Highest Burgrave Kolovrat to create a plan of Prague. It was subsequently made by Jüttner between 1812 and 1815 at a scale of 1 : 4,320. The plan in the form of a large copperplate was published by the National Museum under the title "Grundriß der königlichen Hauptstadt Prag" in 1816.

Intentional changes were made to the depiction of the town fortifications, which were simplified, sometimes omitted, sometimes incorrectly depicted. Elevation is depicted using shading. Jüttner's plan was used in 1826 - 1837 by Antonín Langweil in the creation of his model of Prague.

The plan was published in 1950 in the publication Berní rula sv. 3 modified by PhDr. Václav Hlavsa, including translation into Czech in collaboration with PhDr. Václav Líva.
