BYLT BM 1788 is located about 90 metres south of
the trifinium (which is almost visible in the end of the vista in the left part
of this photo), but here we found the same stone as at LTPLRU. Maybe it was put
here instead since the trifinium was wet?
left Polish border marker, to right Byelorussian border marker - and in the
middle a trifinium marker (?).
