In 742 A.D. St. Boniface founded the bishopric of Würzburg and named St. Burchard as first bishop. Marienberg Fortress is the landmark of the city. The Marienkirche church was built on the original stronghold in 704 and, around it, at the start of the 13th century, the first fortified castle was erected. This medieval fortress was then the seat of the Prince-Bishops for more than 500 years. Everywhere in Würzburg masterworks created by renowned artists such as Tilman Riemenschneider, Balthasar Neumann and Giovanni Battista Tiepolo can be admired. First and foremost the Residenz, former Palace of the Prince Bishops, a splendid Baroque edifice, built by Balthasar Neumann. The Residenz is listed as a UNESCO World Heritage Site as one of Europe's most precious architectural treasures. Also well worth seeing is the cathedral of St. Kilian - Germany's fourth-largest Romanesque church. The artistic highlight here is the tombstone of Prince-Bishop Rudolf von Scherenberg created by Riemenschneider. Art and culture have always been an integral part of life in Würzburg. Especially manifold is the range of classical concerts, such as the Mozart Festival in June or the Bach Festival in November. Würzburg is also known as the "Gateway to the Romantic Road". It is the metropolis of the Franconian Wine Country, a landscape whose vineyards flank the River Main, and are famous throughout the world. It is Franconian wine that, in perfect harmony with Baroque splendour, always makes a visit to Würzburg a memorable experience.
