von Bülow several times asking him to grant her a divorce, but Bülow refused to concede this. He consented only after she had two more children with Wagner; another daughter, named Eva, after the heroine of Meistersinger, and a son Siegfried, named for the hero of the Ring. The divorce was finally sanctioned, after delays in the legal process, by a Berlin court on 18 July 1870. Richard and Cosima's wedding took place on 25 August 1870. On Christmas Day of that year, Wagner arranged a surprise performance (its premiere) of the Siegfried Idyll for Cosima's birthday. The marriage to Cosima lasted to the end of Wagner's life. Wagner, settled into his new-found domesticity, turned his energies towards completing the Ring cycle. He had not abandoned polemics: he republished his 1850 pamphlet "Judaism in Music", originally issued under a pseudonym, under his own name in 1869. He extended the introduction, and wrote a lengthy additional final section. The publication led to several public protests at early performances of Die Meistersinger in Vienna and Mannheim. Bayreuth (1871–1876) In 1871, Wagner decided to move to Bayreuth, which was to be the location of his new opera house. The town council donated a large plot of land—the "Green Hill"—as a site for the theatre. The Wagners moved to the town the following year, and the foundation stone for the Bayreuth Festspielhaus ("Festival Theatre") was laid. Wagner initially announced the first Bayreuth Festival, at which for the first time the Ring cycle would be presented complete, for 1873, but since Ludwig had declined to finance the project, the start of building was delayed and the proposed date for the festival was deferred. To raise funds for the construction, "Wagner societies" were formed in several cities, and Wagner began touring Germany conducting concerts. By the spring of 1873, only a third of the required funds had been raised; further pleas to Ludwig were initially ignored, but early in 1874, with the project on the verge of collapse, the King relented and provided a loan. The full building programme included the family home, "Wahnfried", into which Wagner, with Cosima and the children, moved from their temporary accommodation on 18 April 1874. The theatre was completed in 1875, and the festival scheduled for the following year. Commenting on the struggle to finish the building, Wagner remarked to Cosima: "Each stone is red with my blood and yours".
