The Biblioteca Comunale Ariostea is located in the Palazzo Paradiso in central Ferrara, region of Emilia-Romagna, Italy.
It was named Ariostea, because the collection contains manuscripts related to the author, and within the palace also lies the tomb of Ludovico Ariosto.
In the 17th century as a result of an intervention by Giovan Battista Aleotti was built the clock tower and marble door and the palace received its present appearance.
The library, founded in 1750–1753,[1] and refurbished in 1801 according to a plaque in the reading room,[2] is dedicated to manuscripts and publications related to local writers such as Ariosto, Tasso, Vincenzo Monti, Govoni, Caretti, and Nello Quilici.
The bookshelves and interior architecture were by Gaetano Barbieri, and the ceiling was decorated by Giuseppe Facchinetti, Giacomo Filippi and Alessandro Turchi.
