This is said to be evidence of a Roman castellum in the 4th century near today's Landshut castle ruin. Pointing to this are, among other things, fittings and finds of ceramic and iron underneath the castle. The 12th-century form of the name, Beronis castellum, was a learned re-Latinization, which was related to Adalbero von Luxemburg. Work was begun on the third castle building under the lordship of Archbishop of Trier Heinrich II of Finstingen. On 29 May 1291, King Rudolph I of Germany granted Berrincastel town rights. The castle, Burg Landshut, which was built at that time, was given this name only in the 16th century. In 1332, the town rights were reaffirmed by Emperor Louis the Bavarian's Sammelprivileg (a kind of omnibus decree that dealt with many rights and privileges). Under the terms of the Golden Bull of 1356, Bohemond II became Elector. According to legend, he was brought back to health from a serious illness by a glass of wine, giving rise to the legend of the Berncastler Doctor winery. In 1401, Nikolaus von Kues, also known by his Latinized name Nicolaus Cusanus, was born in Moselle shipowner Henne Cryfftz's house, which is well preserved and can be visited. In 1451, the St.-Nikolaus-Hospital, a hospital for the poor, was built. In 1505, in an Electoral edict from Jakob II, the name Landshut for the archiepiscopal castle crops up for the first time. Emperor Maximilian I spent a night in Bernkastel in 1512 on the way to the Imperial Diet at Trier. The Plague raged in Bernkastel in 1627, and in Kues in 1641. In 1692, Castle Landshut fell victim to fire and since then it has been a ruin. From 1794 to 1814, Bernkastel was a cantonal chef-lieu under French rule. At the Congress of Vienna in 1815, Bernkastel and Kues were annexed to the Kingdom of Prussia. In 1821 Bernkastel became a district seat. In 1848, the Revolution came to Bernkastel as it had to many of the then politically disunited German lands: The black-red-gold flag was hoisted at the town hall and a militia was formed. The first road bridge between Bernkastel and Kues was built between 1872 and 1874, as was the first railway link in 1882 and 1883. In 1891, Bernkastel marked its 600-year jubilee as a town. The town in its current form came into being on 1 April 1905 through the merger
