Casina delle Civette stands out in the park for its unusual and delightful appearance. Over the years, this building has seen many changes. Originally built as a simple retreat away from the main villa, it was redesigned in the early 1900s and then transformed again in 1917. Each renovation added new details and personality to the structure, making it truly unique.
Today, Casina delle Civette functions as a museum devoted to stained glass. The house features twenty rooms, each filled with colorful light and fascinating artwork. Visitors will find 54 stained glass pieces restored and placed just where they once were, bringing the original charm back to the building.
In addition to these, there are 18 other stained glass works collected over the years, displayed on special frames for everyone to admire up close. The collection also includes 105 sketches and preparatory cartoons. Many of these drawings were created for stained glass windows in churches throughout Rome, highlighting the skill and creativity of local artists.
