« My Prince is the best of all instruments. »— Joseph Haydn, Letter to Leopold Joseph Esterházy, circa 1770
Your quest in Eisenstadt begins in front of the Altes Rathaus, built in 1685. This building, with its ornate baroque facade and 1753 clock tower, served as the former town hall before becoming the Burgenland regional museum in 1973. It houses documents from the Esterházy era, linking it to the period when Joseph Haydn, your Kapellmeister, composed for the court. Here you will find the first clues, hidden between the lines of municipal records, leading you towards the princely park.
Continue your investigation at Schlosspark Esterházy, an 8-hectare baroque park created around 1670. The 500-meter main avenue, lined with 18th-century mythological statues, runs alongside the castle and was the scene of many strolls for the princely court. The monumental 12-meter fountain, installed in 1990, is now an open-air concert venue, recalling the musical vocation of the estate. It was in this setting that Haydn found inspiration for his more than 100 symphonies, composed between 1761 and 1790, and where clues are hidden among the 200 recorded tree species.
The heart of your journey leads you to Schloss Esterházy, the main residence of the Esterházy princes, built from 1663. Joseph Haydn served as Kapellmeister here from 1761 to 1790, and the famous 430 sq m Haydn-Saal, known for its perfect acoustics, has been used for concerts since 1762. The princely library, housing 60,000 18th-century volumes, also contains original Haydn scores. As Prince Nikolaus, you explore these places steeped in music and history, where every detail could reveal a part of the musical code you seek.
Your investigation then guides you to the Landhaus Eisenstadt, a palace built between 1668 and 1670 for the Esterházy princes, which became the Burgenland parliament in 1922. Its 110-meter-long facade, with its 365 windows symbolizing the days of the year, is an architectural landmark. The 700 sq m Ritterssaal (Knights' Hall), adorned with baroque frescoes from 1680 restored in 2005, hosted many princely events. It is in its historical archives that Haydn's contracts with the Esterházy family, dating from 1761, are preserved—crucial documents for deciphering the hidden messages.
Finally, your journey through Eisenstadt takes you to the Haydn-Denkmal, a 3.5-meter bronze statue erected in 1928 on Joseph-Haydn-Gasse, facing the castle. A work by sculptor Edmund Hellmer, it was unveiled for the centenary of Haydn's death, who lived in this district from 1761 to 1790. The statue's base bears the inscription 'Dem grossen Meister Joseph Haydn 1732-1809'. This monument, the highlight of your exploration, allows you to finalize the assembly of the coded scores and understand the ingenuity of your former Kapellmeister. Your visit will have highlighted Burgenland's heritage, Haydn's history, and the Esterházy family's role in European musical culture.
