Other striking features include the ambo next to the altar (remains of the late Gothic pulpit), a well-preserved, late-Gothic gravestone in the north aisle (that of Jakob von Brombach, a senior civil servant and church advocate who died in Lahr 1554). There is also a large Mühleisen organ inserted above the portals. This new organ was constructed in three stages between 1969 and 1997 and is based on the famous original Silbermann organ which had been destroyed by a fire in 1877. The present-day appearance of the Collegiate Church dates from extensions and renovations in the 19th century.
