Schloss Elmau & Co - Classic German Hotels
Schloss Elmau in the Allgäu region
Actually it's not a castle, as its name implies. It's a conference venue, founded for that purpose in 1916. Its walls now contain a hotel with a luxury spa, gourmet cuisine and meeting and event facilities. In 2015, the G7 summit took place here. Hotel guests enjoy the luxuriously furnished Alpine retreat in a magnificent setting.
