Some of the most interesting attractions here are around the name of composer Haydn.
If you want to pay respects to Haydn, follow Hauptstrasse to Esterházystrasse, which leads to this church containing Haydn's white marble tomb.
Eisenstadt Haydn Museum
The little home of the composer from 1766 to 1778 is now a museum. Although he appeared in court nearly every night, Haydn actually lived very modestly when he was at home. A little flower-filled courtyard is one of the few luxuries. The museum has collected mementos of Haydn's life and work.
Haydn worked in this chateau erected on the site of a medieval castle and owned by the Esterházy princes. The Esterházy clan was a great Hungarian family with vast estates that ruled over Eisenstadt and its surrounding area. The Esterházys helped the Hapsburgs gain control in Hungary; so great was their loyalty to Austria, in fact, that when Napoleon offered the crown of Hungary to Nic Esterházy in 1809, he refused it. The castle, built around an inner courtyard, was designed by the Italian architect Carlo Antonio Carlone, who began work on it in 1663. Subsequently, many other architects remodeled it, resulting in sweeping alterations to its appearance. In the late seventeenth and early eighteenth centuries, it was given a baroque pastel facade. On the first floor, the great baronial hall was made into the Haydnsaal, where the composer conducted the orchestra Prince Esterházy had provided for him. The walls and ceilings of this concert hall are elaborately decorated, but the floor is of bare wood, which, it is claimed, is the reason for the room's acoustic perfection.
Also various activities are available in this nice small town, such as Ice Skating, Cycling, Bowling, Mountain Biking, Horseback Riding, Hiking etc.
