Contest #966-Luxembourg Solar Circle
The Enscherange Solar Circle, also known as the Kiischpelt Solar Circle, is a unique geographic landmark in northern Luxembourg. It marks the exact point where the full coordinate values of latitude 50.000000° and longitude 6.000000° intersect, making it the only such location in the entire country. This mathematically precise spot lies just outside the small village of Enscherange, within the commune of Kiischpelt.

The site is set in the quiet, hilly Éislek region and is accessible via a pleasant walking route known as the Sun Trail. Visitors arriving at the Solar Circle find a circular paved platform, a metal marker, and a small sundial, all accompanied by an information plaque explaining the significance of the coordinates. The monument stands in open countryside, surrounded by fields and gentle slopes, giving it a peaceful, almost meditative atmosphere.

Although modest in size, the Solar Circle has become a point of interest for hikers, geography enthusiasts, and travelers who enjoy unusual landmarks. It symbolizes the meeting point of astronomy, cartography, and local heritage, offering a rare chance to stand precisely on a whole-number coordinate intersection. The site is freely accessible throughout the year and provides a quiet, scenic stop for anyone exploring Luxembourg’s northern landscapes.

Contest #965 – Saint Sophia Cathedral, Polock, Belarus

The Cathedral of Saint Sophia in Polotsk, built between 1044 and 1066 by Prince Vseslav, is considered the oldest surviving church in Belarus. Dedicated to Holy Wisdom, it paralleled the great Saint Sophia cathedrals of Kyiv and Novgorod. Vseslav, an izgoi prince known in legend as a sorcerer and werewolf, enriched his cathedral with loot from his 1067 raid on Novgorod. Although heavily rebuilt over the centuries, parts of the original 11th‑century structure and the burial vaults of Polotsk princes, including Vseslav, remain. The cathedral originally had seven domes, later reduced to five after a 1447 fire. From the late 16th to early 19th century, it served as the main church of the Ruthenian Uniate Archeparchy.
Repeated fires and wars led to major reconstructions, including a Baroque rebuilding from 1738 to 1765, attributed variously to architects such as Glaubitz, Longhi, or Osikiewicz. The cathedral suffered further upheavals during the Livonian War, the Napoleonic invasion, and World War II. Its religious affiliation shifted multiple times, passing between Greek Catholic, Orthodox, and secular control. Under Soviet rule, it housed an archive and was briefly slated to become a museum of atheism.
Today, the cathedral is part of the State Museum‑Preserve of Polotsk and functions primarily as a concert hall with an organ, though discussions continue about returning it to the Russian Orthodox Church.

Probably the oldest church in the country and chronologically the third carrying the name of the same Saint – each of them now in three different countries.

Contest #964 – Pfälzerhütte, Liechtenstein
The Pfälzerhütte is a mountain hut belonging to the Liechtenstein Alpine Club. It is located at the Bettlerjoch pass at 2108 m above sea level in the Rätikon mountain range in Liechtenstein, directly on the Austrian border.

In 1925, the Association of Palatinate Sections of the German and Austrian Alpine Club was granted permission to build a managed mountain hut on the Bettlerjoch. From the architectural competition held in the autumn of 1926, which received 37 entries, the design by Ernst Sommerlad was selected. Construction took 113 days and cost 93,000 Swiss francs. The hut was opened on August 5, 1928. The first innkeepers were Ida and Hermann Ospelt from Vaduz, who ran the hut for eleven years. During the Second World War, the hut was looted and damaged several times.
After the end of the Second World War, Switzerland became the owner of the hut, and in 1950 it was acquired by the Liechtenstein Alpine Club, which paid 8400 francs for it (including its inventory). The purchase became legally binding in 1952 after Germany waived all claims arising from previous foreign sales. In 1964, the right of use of the hut was regulated between the Palatinate and Liechtenstein Alpine Clubs, who were now entitled to use the hut on an equal basis.
