St. Stephen’s Basilica is the largest church in Budapest and can hold up to 8,500 people. Although in architectural terms it’s a cathedral, it was given the title of ‘basilica minor’ by Pope Pius XI in 1931. It took more than 50 years to build the Basilica. Building commenced in 1851, and the inauguration ceremony took place in 1906 and was attended by Emperor Franz Joseph. During its construction, in 1868 the dome collapsed and rebuilding it had to start almost from scratch, which explains the delay in the Basilica's completion. Architect Jozsef Hild who drafted the original plans and supervised the construction died in 1867. Miklós Ybl, one of Europe's leading architects in the mid to late 19th century, who also designed the Opera House, took over. When the dome collapsed in 1868, Ybl had to draft new plans. Unfortunately Ybl didn’t live to see the completion of the Basilica as he passed away in 1891, however work was finished according to his plans.
Originally designed in neo-classical style by Hild, the Basilica was finished in neo-renaissance style based on the plans of Ybl. The dome is 96 meters high, the exact same height as the Budapest Parliament Building. In fact current building regulations stipulate that no other structure in Budapest can be taller than 96 meters. Having the same height as the Parliament also symbolizes the balance between church and state in Hungary. http://visitbudapest.travel/guide/budapest-attractions/st-stephens-basilica/
