Peipus

Lake Peipus sits on the border and is the biggest transboundary lake in Europe.

Estonia shares a border of roughly 180 miles with Russia, much of it in the middle of Lake Peipus.

Asked by one of the journalists why the area was restricted, a security officer pointed at Estonian territory across Lake Peipus.

Tourists still flock to the sandy beaches and fish-filled waters of nearby Lake Peipus.

Simultaneously, another war, also an heritage from Charles IX., had been proceeding in the far distant regions round lakes Ilmen, Peipus and Ladoga, with Great Novgorod as its centre.
