Jacob Raab made out of the damaged organ's remains a prospect in mannerism style with some baroque elements complemented latter by other masters. Today the vocal organ is more than a century old; it is built by the German firm E.F. Walcker & Sons in Ludwigsburg in 1882-83 and it was inaugurated on January 31, 1884. In 1983 the organ was reconstructed by Flentrop Orgelbouw of Zaandam, Netherlands, so it retained its distinctive sound and look. During the reconstruction the organ was completely dismantled and then reassembled, the second console was restored and later added three stops.
