The Battle of Grobnik field is a legendary battle that supposedly occurred in 1242 between the Croats and the Tatars. The legend was recorded as late as the 16th century and was later a focus of an early romantic poem Grobnik field (near Rijeka) written in 1842 by Dimitrija Demeter for the 600th anniversary of the battle. Legend has it that, in a last-ditch struggle, Croats from all over the region gathered there and killed thousands of Mongols, who withdrew, never to return.
