A longtime haven for artists and writers, this castle (a National Monument) was erected in 1916. Since then it has hosted a G7 summit as well as 220 annual concerts and literary events. The food offer is Michelin-starred with French and Japanese dining courtesy of chef Christoph Rainer at Luce D’Oro and many other eateries dotted around the expansive site. Deep in the Elmau Valley, Schloss Elmau now includes a newer wing, accommodating many of the suites, a spa, a yoga pavilion and a library. There’s also a kids club and a huge bookshop.
