* Old stone walls: In many parts of the world, particularly in rural areas, old stone walls mark former fields or property lines. These walls are often no longer used for agricultural purposes but still stand as a reminder of past land use.
* Abandoned railway lines: These can be seen as relict boundaries because they often demarcate former transportation routes. While the tracks might be gone, the embankment, bridges, and tunnels often remain.
* Former military lines: For example, the Berlin Wall was a physical boundary that divided East and West Berlin. After its dismantling, the Wall was largely removed, but some remnants remain as a reminder of the division.
* The Great Wall of China**: While still standing and partially in use, large sections of the Great Wall are no longer functional as a defensive structure. It's still considered a relict boundary because its original purpose is no longer fulfilled.
The most prominent example of a relict boundary is the boundary between the United States and Canada**. This boundary was established in 1783 with the Treaty of Paris. It is a physical boundary marked by various features like the St. Lawrence River, the Great Lakes, and the 49th parallel. However, since the establishment of this boundary, the significance of the border has changed considerably. While the border still exists, the relationship between the two countries is no longer as tense as it was in the past. The border now serves primarily as a marker of shared culture and history.
