The opera has inspired other works of art. King Ludwig II of Bavaria named his castle Neuschwanstein Castle after the Swan Knight.
The literary figure of Lohengrin first appeared as a supporting character in the final chapter of the medieval epic poem Parzival of Wolfram von Eschenbach. The Grail Knight Lohengrin, son of the Grail King Parzival, is sent to the duchess of Brabant to defend her. His protection comes under the condition that she must never ask his name. If she violates this requirement, he will be forced to leave her. Wagner took up these characters and set the "forbidden question" theme at the core of a story which makes contrasts between the godly and the mundane, and between Early Middle Age Christendom and Germanic paganism.
The most popular and recognizable part of the opera is the Bridal Chorus, colloquially known as "Here Comes the Bride," usually played as a processional at weddings.
