Medvėgalis (in Lithuanian pronounced as /mʲɛd̪vʲeːgaːlʲis/) was a 14th-century fortress in Samogitia, located in present-day Šilalė District Municipality, Lithuania. Its remnants consist of two peaks: Medvėgalis Mound (Medvėgalio kalnas) and Medvėgalis hill fort (Medvėgalio piliakalnis). It was first mentioned in 1316 in written texts and was one of the area's most important and strongest Lithuanian forts. It was attacked by the Teutonic Knights over 20 times throughout history, including the Siege of Medvėgalis in 1329, when it fell to the Teutonic forces and its defenders were converted to Catholicism.[1] thumb|600px|center|Medvėgalis Mound (left) and Medvėgalis Hillfort (right)
