Tiberius Mangold commissioned the Austrian architect to create a plan for a new abbey church. Thumb's plans were extensive, including four courtyards, and the existing Church of St. Magnus was to be renovated. Further work was made impossible by the War of the Spanish Succession, which began in 1701 and cost the monastery 297,000 gulden between the quartering of soldiers and monetary seizures. It wasn't until 1714 that Abbot Tiberius was able to continue his renovations, placing an order for new choir stalls from the master Swabian woodcarver . The delivery of the stalls in 1717 began a remodeling of the abbey church in the Baroque style that would last until 1748. On 20 March 1748, famed Baroque architect Dominikus Zimmermann submitted a plan for the New Monastery. With that plan came a scale model with an area of by and removable floors and roofs. His workshop made another model in 1760 of the outer area and its two complexes of workshops. Zimmerman and his brother Johann Baptist had already worked for Schussenried Abbey at from 1727 to 1733. Zimmermman's plans were accepted, but a local, Jakob Emele, was charged with their execution in 1749. Only about a third of Zimmerman's designs were made reality before the monastery ran out of funds in 1763, and the abbot dismissed. The 16th century courthouse was replaced with a prison built in 1758. Secularization In 1803, Napoleon Bonaparte annexed the Left Bank of the Rhine, and compensated disadvantaged German princes with the territories of smaller states in the former Holy Roman Empire. Among the former were the Counts of Sternberg-Manderscheid, who received the Imperial Abbeys of Schussenried and Ochsenhausen. Schussenried Abbey was awarded to the county on 25 February 1803, and it became a residence for the Counts of Sternberg-Manderscheid. The Counts kept 18 of the 30 monks to look after its grounds, but sold much of the Abbeys' inventory and demolished its eastern portion. Three years later, Sternberg-Manderscheid was mediatized into the newly raised Kingdom of Württemberg, to whom the Counts sold the Abbey on 1 April 1835. King William I, as part of his social welfare programs, established a foundry in 1840 and a nursing home in 1875 on the abbey grounds. The nursing home became the State Psychiatric Hospital of Bad Schussenried, where Gustav Mesmer was held until 1949. The hospital moved out of the New Monastery in 1997, and
