Vestibule of Church of St. Simon and Judas by Childish
Only the vestibule (Domvorhalle) of the Collegiate Church of St. Simon and Judas (Stiftskirche St. Simon und Judas) remained till our days. The church itself was built in 1047 simultaneously with the Imperial palace. The vestibule itself was built a century later in 1151. The church was used as a model of many Romanesque churches all around Germany. It also had a big influence in the church politics.The church was demolished in 1820.
Here you may see the plans how the church looked like: http://www.pe.tu-clausthal.de/agbalck/dom/dom-poster.pdf and plans for the reconstruction.
