The former palace of the ruling princes reigns over the town. Built in the baroque style between 1663 and 1672 on the foundations of a medieval castle and later modified, it is still owned by the Esterházy family, who lease it to the provincial government for use mostly as offices. The Esterházy family rooms are worth viewing, and the lavishly decorated Haydn Room, an impressive concert hall where the composer conducted his own works from 1761 until 1790, is still
used for presentations of Haydn's works, with musicians often dressed in period garb. The hall is one of several rooms on a guided tour (in English on request if there are at least 10 people) that lasts about 30 minutes. The cellar has a large wine museum with 700 objects including a massive wine barrel and historical grape press. A tour of the princess's apartment was added in 2012 and includes objects relating to three royal women. The park behind the Schloss is pleasant for a stroll or a picnic, and in late August it's a venue of the Burgenland wine week—Eisenstadt hosts the "Festival of 1,000 Wines"—and there's a two-hour tour on wine and culture at the palace. It ends with a tasting. Inquire at the information desk.
