Palazzo Benincasa, Gothic palace in Ancona, Italy

Palazzo Benincasa is a Gothic palace in Ancona, built from 1446 for Dionisio Benincasa and designed by Giorgio da Sebenico. Its facade runs over fifty metres along the curve of Via della Loggia, with a ground-floor ogival portico mixing brick and white Conero stone, and two brick upper floors with rows of bifora windows.

Architect Giorgio da Sebenico designed the palace in 1446 for Dionisio Benincasa, a leader of a prominent shipowner and merchant family. Its construction reflects Ancona's economic prosperity during that era as a major trading port.

The Benincasa were among Ancona's oldest shipowning and merchant families, and Dionisio had the palace built from 1446-47. In 1669 Marquis Luciano Benincasa opened his own library to the public; in 1749 the widow Eleonora Vincenzi donated it to the city with 2,634 volumes and two globes, founding the civic library.

The palace sits centrally in Ancona and is easily accessible on foot, with the facade clearly visible from the street. Visitors can admire the exterior architecture and arcades without needing tickets, as they are accessible from outside.

During the 18th century, artist Giuseppe Pallavicini painted detailed interior frescoes showing Ancona as it appeared in his time. These wall paintings serve as valuable visual records of how the city looked during that historical moment.
