The major attraction of Eisenstadt is the Esterházy Palace. Its origins go back to a castle of the 13th
century, which since then was continually remodelled and extended. In
1649, the castle came into the hands of the Esterházy family and in the
second half of the 17th century was remodelled under Prince Paul I into a
baroque palace. It was to be the main residence of the family for more
than 300 years.
