19th Century

1829 In the park of Rosenstein Palace, which has just been built, mineral springs are discovered. King Wilhelm I of Württemberg (1781 – 1864) plans the construction of a "Bathhouse in Moorish style" in the palace gardens, in addition an orangerie and a glasshouse.

1837 Architect Karl Ludwig von Zanth (1796 – 1857) is entrusted with the planning. Because the king hesitates to raise the large sum needed for such an ambitious project, years will pass before the first Wilhelma building is finished. The project is often even in danger of being ditched altogether.

Around 1842
The construction of the first building begins. According to the king's wishes it is given the name "Wilhelma". Architect Zanth knows how to enthuse the king for his ideas, so these are carried out in spite of all resistance. Thus the "bathhouse" becomes living quarters with several rooms. Among these is a cupola hall as well as two adjacent glasshouses, each with a corner pavilion.

1846 On September 30th 1846, Wilhelma is formally opened on the occasion of the wedding of Crown Prince Karl and the daughter of the Tsar, Olga Nikolajevna.

1851 The Moorish banqueting hall is completed. Both of the main buildings are linked by a covered walkway.

1853 With the gallery building and the conservatory the heart of Wilhelma is completed according to Zanth's plans.

1864 After Zanth's death (1857), the Damascene Hall is built according to the plans of the Architect Wilhelm Bäumer. And with this, the construction of the historical Wilhelma is completed. King Wilhelm I of Württemberg also no longer lives to see its completion. He dies in the same year.

1880 Wilhelma by and by is no longer used exclusively as private gardens by the royal family. With a special admission ticket everybody was allowed now to visit the parc.
