The Herľany geyser in eastern Slovakia is a rare cold-water geyser whose eruptions are driven not by geothermal heat but by natural carbon dioxide rising from deep geological layers.

Located near the village of Herľany (German: Herlein, Hungarian: Ránkfüred or Herlány) at the foot of the Slanské vrchy, it has been active since the 19th century, when a spa well unexpectedly transformed into a periodic eruptive spring. Its water column can reach 10–15 meters, shooting upward in a powerful jet that lasts roughly 20–30 minutes. The interval between eruptions is long and irregular, typically around 32–36 hours, which gives the site an air of anticipation and makes each eruption a small event for visitors. The water is cool, mineral-rich, and slightly effervescent due to dissolved CO₂, reflecting the volcanic origins of the surrounding landscape.

Historically, the geyser became a scientific curiosity and a regional attraction soon after its discovery, drawing both spa guests and geologists. According to average eruptive activity data, the geyser erupted over 40,000 times in its 120 years of activity. It remains one of the few cold-water geysers in Europe and is protected as a natural monument. The surrounding parkland preserves the atmosphere of the old spa era, with walking paths and remnants of 19th‑century facilities. Today, the geyser stands as a geological rarity that blends natural spectacle with the cultural history of Slovak spa traditions.

And this ends the “Unvisited Europe” series.
Maybe some of you have recognised the theme on the way.
Now we have covered all countries of Europe (except for the microstate of Monaco, where I found no image of interest that is not recognised by a reverse image search engine).

Congratulations to the winners of this series for their perfect score of 20/20:

Seduvos Malūnas is a mill in Šeduva built in 1905 that burned during construction, stood ruined for decades, and was repeatedly repurposed before its full restoration in the early 2000s. Construction began in 1905, when a new mill was planned for the growing town, but a fire destroyed the structure before completion.
The building survived the upheavals of the early 20th century yet suffered further wartime damage, after which it remained largely abandoned. In 1967, during the Soviet period, the derelict mill briefly returned to life as an entertainment venue, attracting crowds like a festive fairground. After this short revival, it again fell into neglect and slowly decayed.
A major turning point came in the early 2000s, when a full restoration transformed the ruin into a restaurant, event space, and small hotel, preserving its historic silhouette while giving it a new cultural role. The renewed complex incorporates symbolic design elements—especially motifs built around the number seven, considered a sign of luck—intended to create a harmonious atmosphere. Today Seduvos Malūnas stands as a revived landmark, blending industrial heritage with hospitality and reflecting Šeduva’s resilience in reinventing its historic spaces.

Yet another famous tree, the Jesus Tree of Malta, also known as the Crucifix Tree, is a once‑famous pine tree that stood at the base of Telgħa tas‑Saqqajja near Mdina. According to local tradition, the tree was struck by lightning decades ago, and the damaged trunk took on a form that many Maltese believed resembled Jesus Christ on the Cross. This resemblance turned the tree into a small pilgrimage site, where people left candles, flowers, and handwritten prayers. It became a well‑known roadside landmark for those heading toward Mdina or Ta’ Qali, frequently appearing in guidebooks and travel blogs.

Over time, the tree’s condition deteriorated, and the original trunk eventually collapsed, but its memory remains deeply rooted in Maltese folklore. Today, the site is still marked and visited, with plaques and small memorial elements preserving the story. The legend continues to fascinate visitors, blending natural curiosity with spiritual symbolism. Although the Catholic Church does not recognize such apparitions as public revelations, the tree remains a cultural icon, illustrating how local belief and landscape intertwine in Malta’s heritage. The spot at Telgħa tas‑Saqqajja thus endures as a quiet reminder of a once‑living symbol that captured the imagination of generations.
