Castello della Giovannina, 16th century castle in San Giovanni in Persiceto, Italy.

Castello della Giovannina is a noble residence near San Matteo della Decima, in the municipality of San Giovanni in Persiceto, on the border with Cento. It is called a castle because of its crenellated towers, which recall the quadrangular castle form of medieval tradition. The imposing palazzo was built around 1565 for Ercole Aldrovandi and largely remodelled between 1897 and 1902 by the architect Giuseppe Ceri, who also added the oratory.

The villa takes its name from Giovanni II Bentivoglio, lord of Bologna, who commissioned it in 1490 from Sebastiano Serlio; it was built in 1504. Ercole Aldrovandi had the large palazzo erected around 1565. Architect Giuseppe Ceri gave the complex its present appearance in restorations between 1897 and 1902, when the oratory was also built.

The frescoed halls are attributed to Guercino (Giovanni Francesco Barbieri) and pupils of his workshop, painted between 1617 and 1632. The cycles illustrate literary works: Ariosto's Orlando furioso, Tasso's Gerusalemme liberata, Virgil's Aeneid, Guarini's Il pastor fido and Tassoni's La secchia rapita. The name Giovannina honours Giovanni II Bentivoglio, lord of Bologna, who commissioned the building from Sebastiano Serlio in 1490.

The entire structure is currently closed to visitors due to severe damage from the 2012 earthquake. Restoration work is still in progress, so access to the interior and detailed views remains unavailable.

The name recalls Giovanni II Bentivoglio, lord of Bologna, who in 1490 commissioned Sebastiano Serlio to build the residence; it was completed in 1504. The crenellated towers, unusual for a noble residence, are why it is also called a castle. The 20 and 29 May 2012 earthquakes damaged the towers and the small bell tower of the adjoining chapel.
