Historical Significance

Early Historical Context

Rozhledna Ostrá horka, located in the Brno-sever district of Soběšice, stands on a site steeped in historical significance. The hill, also known as ‘Strom,’ reaches an elevation of 405 meters above sea level. The area is notable for its historical landmarks, including the remnants of the Chapel of the Holy Cross (Kaple sv. Kříže), which was built in 1718 and demolished in 1784. This chapel was not just a religious site but also a crucial point in the early development of geodetic science in the region.

The First Trigonometrical Point

One of the most significant historical aspects of Ostrá horka is its role in the establishment of the first trigonometrical point on the territory of what is now the Czech Republic. In 1759, Austrian cartographer Josef Liesganig selected the site as the northernmost point of the trigonometric network based on the Vienna meridian. This network was essential for accurate mapping and land surveying in the Habsburg Empire. The original trigonometrical point was marked by the dome of the Chapel of the Holy Cross. After the chapel’s demolition, a granite block with a commemorative plaque was installed to mark the location.

Construction of the Observation Tower

The modern observation tower, Rozhledna Ostrá horka, was constructed thanks to the efforts of a local group known as the Soběšická garda. The initial steps towards building the tower began in 2004, with the foundation laid in December 2005. The steel structure of the tower was erected over three weeks in November 2007, and the tower was officially opened on December 6, 2007. The public was granted access to the tower on June 1, 2008.

Architectural and Technical Details

The observation tower is a 19.1-meter-high steel structure with two viewing platforms. The first platform is situated at a height of 8 meters, and the second at 16 meters, accessible via a spiral staircase with 90 steps. The tower offers panoramic views of Brno, Babí lom, the Moravian Karst, and the Drahanská Highlands. On exceptionally clear days, visitors can even see the Schneeberg mountain in Austria.

Commemorative Elements

In addition to the observation tower, the site features a small stone memorial that marks the location of the first trigonometrical point. This memorial consists of a granite block measuring 40×40×160 cm, with 110 cm protruding above the ground. The block bears two plaques - one commemorating the original trigonometrical point established by Josef Liesganig in 1759, and the other marking the center of the Chapel of the Holy Cross.

Cultural and Scientific Impact

The establishment of the first trigonometrical point at Ostrá horka had a profound impact on the development of geodetic science in Central Europe. It facilitated more accurate mapping and land surveying, which were crucial for various scientific, military, and economic purposes. The site remains a testament to the early advancements in geodetic science and the historical significance of the region.
