The first point trigonometric Republic

A beautiful view

Nice place for a hiking trip from the northern part of Brno. When the weather comes out there is a great view from the lookout tower.

Taken from the Webmaster. In the mid-18th century, measurements were made in different parts of the world to measure the shape and dimensions of the Earth more precisely. Empress Maria Theresa also instructed the then director of the Vienna Observatory, Josef Liesganig (1719-1799), to determine the length of one degree on the meridian of Vienna, under the influence of the French degrees. Liesganig chose an open terrain between Brno, Vienna, Graz and Varaždin for this work, which began in 1759, in which he set a chain of 22 triangles along the Vienna meridian in a range of about three widths. He chose mostly churches, chapels, or buildings in high places beyond the top points and did not require special signage. The starting point of Liesganig's gradual measurement in Moravia was the tower of the chapel Sv. Crosses in the area of ​​Soběšice, north of Brno (today the territorial part of Brno), in the locality of Ostrá horka, at the top of the hill Strom (404 m). Kaple Sv. The cross, built between 1716 and 1718, was demolished in 1786. It was not until the 1950s that Liesganig's measurement of the accuracy of Liesganig's measurements found the foundations of the chapel, a stabilization stone and a granite prism with two memorial plaques. On one of them is the inscription: »The center of the chapel. The first trigonometric point in the territory of the Czechoslovak Republic, directed by Dr. J. Liesganige in 1759. The new marking was carried out by the Geodetic Service of the Czechoslovak Republic 200 years after its creation. On the other plate is written: »The center of the chapel Sv. The crosses from 1718, demolished in 1786. When uncovered its foundations in 1958, they co-operated under the supervision of ing. Šimka a Dr. Lad. Bartoš of Brno, citizens of the Czech Republic. « The entire history of the finding, reconstruction and commemorative marking of this first trigonometric point on the territory of the then Czechoslovakia was elaborated in detail by the Brno geodet engineer František Hlaváč (1912 - 1993). Over time, however, the monument and its surroundings dwindled, the hill grew trees and bushes, and the visitor could hardly understand why Josef Liesganig chose this place for his measurements when he did not see anywhere from the top of the overgrown hill. This situation led in 2003 to a group of Sobe citizens to set up the Soběšická garda initiative, which aims to restore the lost of dignity of European significance.

A quite inconspicuous stone, located next to the observation tower Ostrá horka on the site of the original Chapel of St. Cross.
