BUDAPEST - St. Stephen's Basilica

St. Stephen's Basilica (Hungarian: Szent István-bazilika) is a Roman Catholic basilica in Budapest, Hungary. It is named in honour of Stephen, the first King of Hungary (c 975–1038), whose right hand is housed in the reliquary. It was the sixth largest church building in Hungary before 1920. Since the renaming of the primatial see, it has been the co-cathedral of the Roman Catholic Archdiocese of Esztergom-Budapest. Today, it is the third largest church building in present-day Hungary. - via: Wikipedia
