Austrian and Czech Baroque influence. This is most evident in the two churches, which resemble the of Kuks and the of Steyr. The palace's two Baroque architects, Johann Friedrich Nette and Donato Frisoni, were educated and worked in Bohemia and hired staff experienced in the Bohemian style. Frisoni even knew or was related to some of the artisans who worked at the Steyr church. French influence is also present, for example in the mirror halls in both the corps de logis and the palace's many mansard roofs. The combination of work by Germans (Philipp Jenisch and Nette) and Italians (Frisoni, Diego and Carlo Carlone, , Scotti and Luca Antonio Colomba) produced a strong resemblance to late 17th century works in Prague and Vienna. Charles Eugene brought the Rococo style to Ludwigsburg in 1747 and his court architect, Philippe de La Guêpière, worked in that style until 1775. Nikolaus Friedrich von Thouret, working with Antonio Isopi, renovated much of Ludwigsburg Palace for Frederick I and Charlotte Mathilde from 1797 to 1824. Thouret's work was heavily influenced by the French Imperial and Renaissance styles, the work of Charles Percier and Pierre François Léonard Fontaine, and Egyptian motifs that became popular in Europe with Napoleon's three-year Egyptian campaign. Isopi would simplify Thouret's plans, which were then carried out by the Biedermeier woodworker Johannes Klinckerfuß and court painter Jean Pernaux. As a result, the palace's Neoclassical architecture does not reflect a single style or correspond to any one designer. North wing (Alter Hauptbau) The north wing, referred to as the Alter Hauptbau (Old Main building), is the oldest portion of the palace. It was originally built to house the apartments of Eberhard Louis and Princess Henrietta Maria. Its facade was built from 1705 to 1708 and its interiors were mostly completed by 1715, although work inside its pavilions lasted into 1722. In 1809, and from 1826 to 1828, the rooms facing the courtyard in the beletage (main floor) were remodeled in the Neoclassical style, but their Baroque frescoes were revealed in 1865. The corps de logis opens with a wide vestibule, decorated by Frisoni in 1712, that terminates in an unadorned staircase. At the top of the stairs is a guard room and the four suites on the beletage. These follow the French Baroque model of a living room, audience chamber, and bedroom. Eberhard Louis's apartment features a hall of mirrors decorated with stucco
