 In the Kingdom of Poland, the village of Mosty was a royal property, with its own starostas.The village itself was established in 1472, and was part of Belz Voivodeship.In the late 15th century, Mosty was ransacked and destroyed in a Crimean Tatars raid, and in July 1497, during the Moldavian expedition of John I Albert, a unit of Teutonic Knights under Johann von Tiefen, called upon by the Polish king, marched through the village.
