Karlsburg Castle
Karlsburg Castle is the former margravial residence in the Durlach district of Karlsruhe, expanded from 1563 and largely rebuilt after the 1690s. Only the Prinzessinnenbau (Princesses' wing) of the historical building survives today; the site now houses museums, municipal offices and a library. The surviving wing and courtyard retain a compact palace silhouette attached to older stonework and an open paved forecourt.

As it stood in 1688
What Karlsburg Castle looked like in its prime.
A compact pale-yellow plastered palace wing with regularly spaced rectangular windows and white surrounds stands beside a small cylindrical turret with a conical red-tiled roof and narrow mullioned windows with red frames. The wing meets older rough-hewn stone fragments at its base and fronts onto a wide cobbled forecourt dominated by a low circular fountain. Steep red clay-tile rooflines, restrained rectangular window bays and mature trees behind the stonework complete the enclosed courtyard silhouette.
Its story
The story of Karlsburg Castle.
Karlsburg Castle has shaped the history of Baden since 1563, when Margrave Charles II abandoned his residence at Pforzheim for Durlach and extended the medieval castle into a palace. His successors kept enlarging it until 1689, when French troops occupied Durlach and burned both the city and the castle.
Margrave Frederick Magnus returned from exile in Basel in 1698 and began rebuilding, but the war-devastated margraviate had no money and the citizens of Durlach refused to support the work. Two wings were finished by 1703, then the project was suspended indefinitely. His son Charles III William settled the matter in 1715 by founding Karlsruhe around a new palace, moving his court there in 1718, though his wife stayed on at Durlach until her death in 1743.
The Karlsburg later served as administrative offices and even a barracks; the Pfinzgau Museum has occupied it since 1924, a wing was demolished in 1964 to make room for a school, and a long renovation ran from 1973 to 1988. Only the Prinzessinnenbau, the Princesses' wing, of the historical building still stands, now housing the registry office, two museums, the historic banquet hall and Durlach's city library.
