Views of Xiamen, PRC, from Kinmen County, ROC, and vice versa.
I'm looking to bag this one soon and remain skeptical that these three pictures- the first two from wikipedia commons dated 1994 and the third from the corner corner forum in 2001- are the only pictures on the internet of Boundary Marker 583.
I feel like there was a flickr(?) album out there of a much more detailed report more recently but for the life of me I cannot find it. It may have been for a different international tripoint.
If anyone has info on this one it would be great to dig up. It doesn't seem difficult to access technically but for this marker to only have three pictures and none from the last quarter century just seems crazy.
Most people walk across the runway - I did that too. In case a plane lands, the gates are closing, and you have to wait until all is clear again.
In the background you can notice the two colourful rods flanking the road - the blue and white one representing the german Free State of Bavaria while the black, red and gold one represents the Federal Republic of Germany. The sign says "Attention - international boundary".
I always imagine a stern voice saying "Passage interdit" when I pass here.
Coordinates demarcate the boundaries of the two sovereign nations
Buildings go right up to the shore in Singapore. There's a university right next to those buildings.
About a mile or 1.5km away, a minute or two on a jetski if you need that perspective

This is the border between Austro-Hungarian and Ottoman influence on architecture in Sarajevo, the capital of Bosnia & Herzegovina. It serves as a boundary between western and eastern cultures. Because the territory was ruled by both empires consecutively, the Ottoman’s established the old city while the Austro-Hungarians expanded and modernized.
A person is living in Portugal on a residency category where they are only allowed to stay outside Portugal for 4 months per year. They want to explore Europe by traveling across Schengen land borders (Spain, France, etc.) and are wondering how movement inside Schengen is practically tracked between countries.
Since many internal Schengen borders have minimal checks, how do authorities usually determine how long someone has been outside their country of residence? Is it mainly passport scans, transport records, hotel records, tax activity, mobile data, or something else?
The question is more about understanding how Schengen movement, geography, and interconnected systems work in practice rather than asking for illegal advice, he/she wants to travel and spend time in different european countries and experience it without being tracked on that 4 months limit. He/She can follow a land crossing border plan as well, like from portugal to spain its fine, then how he/she should be travelling across to other countries
