The "Pasqualatihaus", named after its owner Josef Benedikt Baron Pasqualati, was built in the eighteenth century and is located on Mölker Bastei, part of the remains of the old city fortifications.
Altogether Ludwig van Beethoven worked in Vienna for thirty-five years. Thereof he spent eight years living in this apartment on the fourth floor. The spectacular view over the then still undeveloped site of the fortification approaches towards the northern and north-western suburbs of Vienna kept drawing the composer back to Mölker Bastei after his various short stays in the country.
Here he worked on his 4th, 5th, 7th and 8th symphonies, among others, and above all on his opera "Fidelio". Besides numerous documents illustrating the life and work of Beethoven, there is the famous 1804/05 portrait of Beethoven by Willibrord Joseph Mähler and many personal items owned by the composer.
