The cleits (stone huts) in the image belong to the once-populated, medieval village of Hirta in the Scottish archipelago of St. Kilda located in the North Atlantic Ocean. The sea cliffs in Hirta are the highest ones in the entire United Kingdom.
The village was never packed with people: its number of residents varied between a few dozen and almost 200 residents for a few centuries. It was finally evacuated in 1930 due to illness brought by tourists and the First World War. Nevertheless, it remains a popular destination among scientists and conservation workers.
The St. Nicholas Church in North Macedonia
The partially submerged St. Nicholas Church is located in the national park of Marvoro in North Macedonia, not next to, but inside the Marvoro Lake. This lake was artificially created in the 1940s when the Marvoro River was dammed, submerging some buildings in the area.
The St. Nicholas Church was the only one of those buildings to remain standing (well, kind of). The fact of it being submerged (or not) actually depends on the amount of rainfall the area gets. Surprisingly, when it's not submerged, people can come inside and have a look.
The Grand Theater in Lebanon
This formerly magnificent, abandoned theater, also called the Grand Théâtre des Mille et Une Nuits, is located in the city of Beirut in Lebanon. Built in the 1920s as part of a larger commercial center and featuring no less than 630 seats, it hosted both film productions and international performances from various countries, like the French Ballet des Champs-Elysées and legendary Egyptian singer Um Kalthoum.
In the image, one can see its uniquely decorated domed ceiling. During the Lebanese civil war, it suffered severe damage and went out of use.
The Ghost Town of Berlin in Nevada
The Berlin, NV ghost town, built in the 1890s, is now part of the Berlin-Ichthyosaur State Park on Highway 50. A large portion of the town's buildings was preserved (not in top shape, obviously), as well as some old vehicles and other historic items.
This image shows an old car that we can only imagine was once driven by a former town resident.
The Kilchurn Castle in Scotland
The ruins of the Kilchurn Castle can be found in Loch Awe, Argyll, and Bute, Scotland. Built in the 15th century to serve as a base for the Scottish Clan Campbell, it was later abandoned by members of the clan and ruined by 1770.
During the summer, visitors can still come and explore the preserved site and see what's left of the castle, now belonging to the Historic Environment Scotland.
