One of the public buildings in Varese that is well worth a visit is Palazzo Estense, which was the summer and autumn residence and court of Francesco III d'Este, the Duke of Modena and Lord of Varese. It was built to the designs of the architect Bianchi in the second half of the eighteenth century. The “Salone Estense” (Estense Hall) with its large fireplace made from multicoloured marble is quite stunning. Palazzo Estense is now the Town Hall.
Behind the palace are the Estensi Gardens, one of the most charming public parks in Italy, which were built in the same style as the gardens of the Schönbrunn Palace, in Vienna, and finished in 1787.
