Did you know that this unassuming structure before you holds a fascinating secret? This is the Pacoldova vápěnka a former industrial complex in Prague-Velká Chuchle. It stands as a testament to ingenuity and a unique piece of Czech industrial heritage.
The Pacoldova vápěnka gets its name from Professor Jiří Pacold a prominent figure in Czech technology. His innovative patent in the late 19th century revolutionized limestone processing. Unlike previous methods Pacold’s invention allowed for the use of unsorted limestone a significant advancement for the time. This clever innovation is what makes the Pacoldova vápěnka so special. It’s more than just a lime kiln it’s an embodiment of a technological leap.
Construction of the Pacoldova vápěnka likely began before 1880. That was when the construction of this type of kiln ceased. This lime kiln continued to operate until the early 20th century. After World War I it experienced a brief revival. Production halted permanently in 1938. Subsequently the site fell into disrepair. Its walls crumbled. Precious brickwork was even lost.
The Pacoldova vápěnka is comprised of two double shaft kilns. Limestone was extracted from a nearby quarry. A narrow-gauge railway transported the raw material to the kilns. Inside the kilns you’d find three rotary furnaces. These furnaces were positioned at a third of the kilns height. At the base were two discharge openings. Sadly the original hoists and lifting mechanisms are no longer extant.
Despite its deteriorated condition the Pacoldova vápěnka became a recognized technical monument in 1966. However its neglect continued. The site was even used as a location for filming comedies and detective stories. A notable example is Martin Frič’s “The Secret Premiere”.
In the late 1970s the Pacoldova vápěnka came under the protection of the Prague 5 District National Committee. A proposal for its use as a production facility for specialty materials was considered. Ultimately this proposal failed due to emissions from a nearby cement plant. Thankfully further efforts by the National Technical Museum saved it from demolition. This resulted in fundamental conservation work and the Pacoldova vápěnka’s survival.
After 1989 the Pacoldova vápěnka was returned to private ownership. Essential repairs were carried out by the new owner. The structure now stands as a protected cultural monument of the Czech Republic. A testament to both innovation and preservation. A reminder of the industrial past and a unique example of Czech engineering.
