The Venus Grotto (Venusgrotte) is wholly artificial and was built for the king as an illustration of the First Act of Wagner's "Tannhäuser".
Ludwig liked to be rowed over the lake in his golden swan-boat but at the same time he wanted his own blue grotto of Capri.
This artificial cave, built in 1876-1877 by the landscape sculptor August Dirigl, was lit by arc lights. The electricity for this was generated
by 24 dynamos (made by Siemens-Schuckert) in the machine house 100 metres (328 ft) away, one of the first electricity works in Bavaria.
The Venus Grotto features a "Royal Seat", a Lorelei rock and a gilt boat in the shape of a shell.
Schloss Linderhof (Linderhof Palace) is a "Königliche Villa" (Royal Villa) in southwest Bavaria near Ettal Abbey, Germany.
It is the smallest of the three palaces built by King Ludwig II of Bavaria and the only one which he lived to see completed.
