Bourtange, Netherlands
Located in northeast Netherlands, near the German border, Fort Bourtange was built in 1593 as a military fortification to guard the only road connecting Germany and the city of Groningen. Converted into a village in 1851, it retains its iconic pentagonal shape and geometric street pattern. Today, the entire site serves as a museum, preserving its historical and architectural significance.Palmanova, Italy
Palmanova, which lies in the Friuli-Venezia Giulia region in northeast Italy, is listed as a UNESCO World Heritage site. Built by the Venetians to defend the Republic’s northeast border, it is a quintessential example of a Renaissance star fortress and is one of the largest and best preserved geometric towns. Palmanova’s radial design extends from a central hexagonal square, the ‘Piazza del Duomo’, with concentric rings crossed by straight avenues. This internal area is surrounded by a star-shaped double perimeter of fortifications.Almeida, Portugal
Situated on a high plain in northeast Portugal, close to the Spanish border, lies the fortress of Almeida. It played a crucial role in defending Portugal’s border during its early years of independence. As seen in the image, its old town is surrounded by striking star-shaped ramparts.Neuf-Brisach, France
Located in the Alsace region of France near the German border, Neuf-Brisach was built in 1697 on the French side of the Rhine, after the loss of Breisach on the opposite bank. The town’s name ‘Neuf’, meaning new in French, reflects its origins. Designed for both civilian and military use, Neuf-Brisach has a central octagonal layout with streets arranged in a square grid. It is part of the UNESCO listed network of fortifications created by Louis XIV’s famed engineer, Sébastien Le Prestre de Vauban.

Much more defensible during a zombie apocalypse. While the zombies probably wouldn’t be bringing 17th century cannons to bear against your walls, you’d still get superior firing angles for your defenders.
These baboons couldn’t possibly have built these structures. They must have been assisted by aliens.
The green and red hues evoke a Christmas vibe, achieved through different band combinations during image processing to generate true-colour (green) and false-colour (red) visuals.
Does anyone have more insight as to what the red colored band is measuring? The patterning is quite interesting, but the description in the article lacks specifics.
Edit: I think it’s likely infrared or near infrared, but without information about which sattelite those images come from, I can’t be certain.
Yeah, your edit pretty much nails it. The majority of optical imaging satellites use near-infrared in addition to the classic red green & blue channels (& a wider one called panchromatic). Near-infrared is extremely good at seeing plants and vegetation, so the bright red parts will typically be densely vegetated areas like fields and forests.
Looks like these particular images come from GEOSAT and Airbus (I’m guessing one of the Pleiades satellites)
Zwolle
The top left and bottom right look like locations in video games that have been corrupted by some evil shit, with all that red. That’s not what they actually look like is it?
