Regīna Indriķe, an expert at the Rāzna National Park, accompanied Latvian Radio to the scene.
The European ash tree (Fraxinus excelsior), the girth of which measures 5.17m, was perhaps used as a boundary marker for the nearby Asticu manor, a practice Indriķe claimed goes back to the ancient times.
"In Ancient Rome oaks were used as boundary trees for fields and land properties, as - dead or living - the strong, good tree stands upright for a long time," said Indriķe.
The tree could be around 200 years old, she said.
