Despite heavy destruction, in particular during the Second World War, the city's history is clearly evident even in the modern Stuttgart. Architecturally speaking, this can clearly be seen in the Schillerplatz with the Old Castle, which together form a Renaissance ensemble, the Baroque New Castle, as the residence of the Dukes and later the Kings of Württemberg, and Neo-Classical buildings such as the Königsbau.
The Stuttgart City Archive collects information about the city's history. It acts as the "City historical centre", which records and evaluates all the City Council documents, and makes them accessible to the city's population and for research, rather like a "city memorial". It passes on the history of Stuttgart, through its own research, publications, conferences, lectures and exhibitions.
The State Capital is planning to create a City Museum in order to bring the city's history to life more vividly. When the City Library moves out in a few years, the Museum will be housed in the Wilhelms Palace.
