For the inauguration of the Prussian National Monument for the Liberation Wars Frederick William III chose the 30 March 1821, the seventh anniversary of the conquest of the Montmartre in the Battle of Paris. The inauguration was attended by the royal family, the Prussian generality, the senior pastors of all Protestant congregations of Berlin, and as guests by Grand Duke Nicholas of Russia and his wife Alexandra Feodorovna (Charlotte of Prussia), as well as by thousands of other spectators. As the national monument is crowned by an Iron Cross the king renamed Götze'scher Berg into Kreuzberg (i.e. cross hill) on the occasion of the inauguration of the monument.
