Chelm Chalk Tunnels
Lubelskie
The Chelm Chalk Tunnels are a historic chalk mine located beneath the city of Chełm in Poland's Lubelskie region. This extensive underground labyrinth formed over centuries through the mining of writing chalk, with origins dating back to the 13th century after the city's reconstruction by Prince Daniel of Galicia. The tunnels, originally dug directly from residents' cellars, were used not only for chalk extraction but also as shelters during conflicts. Over time, the separate mining excavations connected, creating a complex network estimated at around 40 kilometers, spanning multiple levels up to 20 meters deep. The tunnels showcase unique mining techniques and structural reinforcements specific to Chełm. Today, a 2-kilometer illuminated tourist route runs beneath the old town, featuring exhibits on archaeology, chalk mining, and the city's history, as well as encounters with local bats and the legendary spirit Bieluch. The tunnels maintain a constant temperature of about 9°C and high humidity, offering a distinctive subterranean experience. The site is accessible only with guided tours, ensuring an informative and safe visit.

History
Chalk mining beneath Chełm began in the 13th century following the city's reconstruction.
Initially, chalk was extracted directly from cellars and sold to distant cities, including Kraków.
The mining activity peaked during the 17th and 18th centuries, with many city houses having direct access to the tunnels.
Over time, the underground workings merged into a vast labyrinth extending beyond the city limits.
Due to safety concerns, mining was restricted in the 19th century and completely banned in the early 20th century.
Rediscovered during construction works in the 20th century, the tunnels were gradually secured and opened for tourism, finally being registered as a historic monument in 1995.
