In architecture, bacini (plural, singular Italian: bacino, IPA: [baˈtʃiːno], "bowl"[1]) are ceramic bowls that were used for decoration in the medieval Europe.[2] The bowls were embedded into the external walls of (mostly religious) buildings[3] and are thus also known as immured vessels.[4] Bacini represent one of the traits of the Pisan Romanesque style.[5] They can also be found in the Byzantine and Gothic buildings.[6]
