Point Roberts, in WA, USA is physically unconnected to the rest of the US. It is south of Vancouver, BC, and is US territory by virtue of the fact that it lies south of the 49th parallel.
Llivia, Spain is surrounded by France. Apparently, someone forgot to tell the residents that they were French, when the border was moved, so they carried on being Spanish.
Baarle-Nassau is Belgian, but is within the territory of the Netherlands, except those parts of the town that are Dutch. These are enclosed completely by Belgian territory. Complex, huh?
