Chiemsee / Herrenchiemsee
Chiemsee is Germany's third-largest lake, after Bodensee and Müritz. On the 238-hectare Herreninsel (Gentlemen's Island), King Ludwig II had the New Herrenchiemsee Palace built between 1878 and 1886, modeled after Versailles. Its Great Hall of Mirrors, at 75 meters, is even slightly longer than the Hall of Mirrors in Versailles. Since July 2025, the palace has been a UNESCO World Heritage site.Herreninsel is only accessible by water. Excursion boats from Prien am Chiemsee dock at the Old Palace, the former monastery building. On the smaller Fraueninsel (Ladies' Island), the Benedictine Convent of Frauenwörth has existed since 772.
