on big screens at Stephansplatz. The funeral procession through Innere Stadt was over one kilometer long. Following the procession, Otto was entombed in the Imperial Crypt. A blessing from Pope Benedict XVI was read during the requiem. Otto was the penultimate person to be entombed in the Imperial Crypt, where 145 other members of his family have been entombed since 1633, because the Crypt is almost full. In Bavaria, the ruling Christian Social Union of Bavaria organised the largest commemorations in the state since the death of its former Prime Minister Franz Josef Strauss; the commemorations included the celebration of two requiems and a reception at the Munich Residenz. Otto's coffin was draped with the Habsburg imperial flag in black-yellow and featuring the imperial-royal coats of arms of Austria and Hungary in addition to the Habsburg family coat of arms. Otto von Habsburg wrote that the funeral of Franz Joseph I of Austria in 1916 had been the most profound experience of his childhood; the 4-year-old had attended the funeral dressed completely in white among all the adults dressed in black. Otto's funeral was organised by his sons, Karl von Habsburg, head of the House of Habsburg, and Georg von Habsburg. Karl von Habsburg revealed that the planning for the funeral had started 12 years earlier, and that Otto had not involved himself in it, except for expressing the wish for a ceremony in Hungary in line with the family tradition. The Imperial Crypt of the Habsburg family is each year visited by around 200,000 people. The Crypt was constructed in accordance with the will of Empress Anna. The sarcophagus of Otto's wife Regina, who was interred in her family crypt in the castle of Veste Heldburg in Germany in 2010, was transferred to Mariazell and then to the Imperial Crypt in Vienna at the same time. However, Regina's heart will remain in her family crypt in Veste Heldburg. The security measures were reportedly massive. Large parts of central Vienna were closed down for public traffic. The small Austrian Green Party criticized the government for the extensive state involvement in the funeral, which made it indistinguishable from a state funeral in their opinion. The funeral was said to have nourished Austria's important tourist industry; according to a study, the imperial Habsburg heritage is the main reason tourists visit the country.
