The Mafra carillons constitute the largest carillon ensemble in the world.[1]
Spanning two 50-metre-high (160 ft) towers in the Palace of Mafra, it features 120 bells, divided into carillon (45 bells in north tower, 53 in the south tower), liturgical and clock bells.[2][3]
Along with the entire Mafra Royal Building (Portuguese: Edifício Real de Mafra) the carillons were inscribed on UNESCO’s World Heritage List in 2019.[4][5]
