Upon his death, in 1336, Cardinal Luca Fieschi - leading exponent of the great Genoese Guelph family - entrusted his will to be buried in the Cathedral of San Lorenzo. On his own will, a grandiose sepulcher was built which was to seal his role as Prince of the Church and head of the Fieschi family. Demolished at the beginning of the seventeenth century, part of the fragments have been recomposed in the Diocesan Museum. It is a grandiose funeral complex created by Pisan sculptors and a symbol of the high quality of Ligurian fourteenth-century sculpture.
