Rüstkammer des Moskauer Kremls
The location of the battlefield was a matter of some contention until 1808, when a peasant woman from Lykovo near Yuriev-Polsky on the Koloksha River discovered an ancient gilded helmet with an image of St. Theodore, the patron saint of Yaroslav Vsevolodovich. The helmet has been preserved in the Kremlin Armoury.
