Does this unsassuming sandstone pillar hold secrets? This is the Meridiansäule. It stands as a monument to a brilliant mind. The Meridiansäule in Dresden-Rähnitz commemorates Wilhelm Gotthelf Lohrmann. He was a German geodist, topographer, astronomer, and meteorologist.
This pillar marks the northernmost point of his survey system. It is a reminder of Lohrmann’s work as a geodist. Lohrmann was born on January 31, 1796. He became known for his moon map, “Mondcharte in 25 Sectionen”. He only published four sheets of it before his death. Other works include Topographie der sichtbaren Mondoberfläche.
This Meridiansäule was erected in 1828. Lohrmann himself initiated its construction. The Meridianstraße in Rähnitz was named after it in 1909. The street serves as a cross connection. It runs from Hellerstraße to Beckerstraße.
The Meridiansäule features a relief panel. This sandstone pillar highlights Lohrmann’s work. Specifically it shows his contributions to geodesy. It served a practical purpose. The inscription says that this pillar marks the northern main point of his coordinate system. This coordinate system would provide a new fundamental measurement. This new measurement should eliminate any arbitrariness in determining property tax.
Imagine Lohrmann. He meticulously surveys the land. He charts the stars. His work aimed to bring accuracy to the world. He wanted to bring accuracy to the measurement of the land. Though less famous than some historical figures, Lohrmann’s work had a lasting impact. He died in 1840.
Today, the Meridiansäule stands as a reminder. It reminds us of precision. It reminds us of the pursuit of knowledge. It also stands as a reminder of the importance of astronomy.
