The mausoleum stands on the peak of Württemberg Hill at the westernmost end of Schurwald woods overlooking the Neckar river. The memorial was built for Catherine Pavlovna of Russia (1788–1819), the second wife of William I of Württemberg (1781–1864). The remains of William I and his daughter Maria Friederike Charlotte of Württemberg (1816–1887) are also housed in the mausoleum.
The mausoleum was built after the death of Queen Catherine between 1820 and 1824 based on a design drafted by Giovanni Salucci. The location on the former site of Burg Wirtemberg was chosen as the home of the House of Württemberg.
The building stands by itself in the middle of the vineyards along the river Neckar making it visible from afar.
The mausoleum is inspired by the Villa Capra "La Rotonda" build by Andrea Palladio. Salucci created a circular structure made from local sandstone with three pillared porticos and steps leading up to it. The entirely with interior has a domed roof. The arrangement of pillars and the colossal statues of the four Evangelists reflect the neoclassical preference for severity and purity of style.
