Radvanice

Radvanice is nestled in the Trutnov District of the Hradec Králové Region, in the Czech Republic, part of Eastern Europe on the Eurasian Plate. This small village, with a population of about 1,000 as of 2018, is not a major city but is significant for mineral enthusiasts. It lies approximately 11 km east of Trutnov and 44 km north-northeast of Hradec Králové, offering a rural setting with nearby localities like Jívka and Trutnov, which add to its regional context.

Radvanice is a treasure trove for mineral collectors, particularly due to the Kateřina Coal Mine. It boasts 88 valid minerals, with three type localities—Pertoldite (GeO₂), Radvaniceite (GeS₂), and Stangersite (SnGeS₃)—meaning these were first described here. Notable minerals include Alacránite, Albite, Antimony, Bismuth, Cadmium, Lead, Uranium, and Zinc. The mine’s burning dump pile has led to unique formations like Galena (with crystals up to 4 cm, some radioactive due to ²¹⁰Pb), Greenockite (acicular crystals ~1 mm, yellow-brown to orange), and Selenium (red-black needles up to 2 cm, likely from mine fires). These rare and visually striking minerals make Radvanice a must-visit for enthusiasts.

The area’s geology is rooted in the Carboniferous period (303-305 million years ago), within the Intrasudetic Basin’s Odolov Formation, Jívka Member (Stefan A - Stefan B). It consists mainly of sedimentary rocks, particularly coal-bearing strata from ancient peat swamps. The burning of the coal dump has created conditions for rare mineral formation through sublimation, adding to its geological interest. Fossils like Adelophthalmus and Anthracomartus radvanicensis, preserved in these formations, offer a glimpse into the region’s ancient past.

The Kateřina Coal Mine was historically significant for coal extraction, with its burning dump pile now rehabilitated and safe, indicating past activity likely during the 19th and 20th centuries, a peak period for Czech coal mining. However, exact dates of operation are not readily available online, suggesting a need for local historical records. The mine’s legacy lies in its contribution to the region’s industrial past and the unique minerals formed from its fires.

Radvanice is a quaint rural village, first mentioned in 1607, reflecting a long history typical of Czech countryside communities. With a population of around 1,000, it offers a glimpse into traditional village life, though specific cultural events or traditions are not well-documented online. Its proximity to Trutnov, with its medieval trade route connections, hints at broader regional cultural influences, but detailed information remains sparse.

Specific climate and ecology data for Radvanice are limited, but it likely shares the temperate climate of the Hradec Králové Region, with cold, snowy winters and mild to warm summers. The area is part of a forested region, with nearby mountains like the Krkonoše influencing local ecology, supporting diverse flora and fauna. Historical mining, particularly the burning dump, may have impacted the local environment, but the site’s rehabilitation suggests efforts to restore ecological balance.
