Eszterháza was first inhabited in 1766, but construction continued for many years. The opera house was completed in 1768 (the first performance was of Joseph Haydn's opera "Lo speziale"), the marionette theater in 1773. Joseph Haydn's concerts typically took place in the Sala Terrena on the ground floor, in the picture gallery, where on May 30th, 1781 a concert was performed in the presence of Duke Albert and Sachsen-Teschen and his spouse, Archduchess Christine. Musical entertainment for the higher ranks was provided in the main building, typically located in the picture gallery ground floor. Regular free-to-attend academies were typically held in the marionette theater, which were open to the public and hosting a whole range of cultural and environmental programmes. The fountain in front of the palace was not completed until 1784, at which point the Prince considered his project complete. The music room was decorated with white and gold walls with delicately rounded corners, the frescoed ceiling, glass chandeliers, roses, and audience's period chairs.
