Livonian gives another kind of feel. It has had more direct Latvian influence, but still is quite different in its lexicon. One of the dialects of Latvian -- the Livonic or Livonian-like dialect (lībiskais dialekts) -- mostly formed where Livonian was spoken. It has even more Finnic features.

I saw this marker from a distance once about a decade ago when I was staying with friends by Lake Gilbbesjávri/Kilpisjärvi, where the boundary marker is located. This picture doesn't show the marker, but the lake is visible. I took it from Sána/Saana -- a mountain nearby with nice views of the lake.
