~• about Schloss Wernigerode

"Christian Ernest's descendant Count Otto, first president of the Prussian Province of Hanover from 1867, president of the Prussian House of Lords from 1872 and German Vice-Chancellor from 1878, had the schloss again extensively rebuilt in a Neo-Romantic half timber and half stone,[3] style known as historicism, finishing the project in 1893. Later when Otto became German ambassador the castle became a representation of North-German historicism. The entire complex includes a chapel built in 1880 by German architect Carl Frühling according to drafts by the renowned Vienna architect Friedrich von Schmidt. The original chapel was inaugurated in honor of patron saint Panthaleon and St. Anna and it was situated on the north-western part of the castle circle. Its baroque shape remained unchanged until its demolition in 1870. The new chapel is located in the same location as the old chapel and was inaugurated in 1883. The historic hall is decorated with built-in galleries, while the choir is decorated with stained glass designed by artist Carl Christian Andrea."
