Hi, Vlad
The location You mention is not in western Ukraine. It is in Northern Greece, the closest city in a modern map seems to be Kato Nevrokopi (closest to the center location of this Kleintrapez which is 41 degrees 22 Minutes 30 Seconds N, 23 degrees 45 Minutes Seconds East). The area would be approximately 9 x 11 kilometers, a link to the center in MapQuest is here:
