Located just 20 miles northwest of Albania’s capital Tirana, the historic town of Kruja lies nestled in the foothills of a stunning mountain of the same name. The name of the city is related to the Albanian word kroi meaning "fountain". Kruja’s other attractions include its medieval castle, the site of national Albania hero Gjergj Kastrioti Skanderbeg’s legendary battle against the Ottoman Turks, and the Skanderbeg Museum; an institution dedicated to chronicling and honoring his life.
