The Buzău Pass was one of the passes used by invaders, such as Turks and Tatars, to attack Transylvania. This is why the nearby region, known as Țara Bârsei was settled by Teutonic Knights in the 13th century, who built fortifications, to be prepared against such an invasion. Nevertheless, many invasions were conducted through the Buzău Pass, including the Turkish attacks of 1421, 1432, 1438, and 1508, as well as the Tatar invasion of 1658. When Ottoman forces or other invaders would break through the pass, the village of Prejmer was the first place they encountered; the village was destroyed over 50 times between the 13th and 17th centuries, while the Prejmer fortified church was only rarely captured.
