While his illegitimate son was killed, Ugolino himself – together with his sons Gaddo and Uguccione and his grandsons Nino (surnamed "the Brigand") and Anselmuccio – were detained in the Muda, a tower belonging to the Gualandi family.
Ketika anak haramnya terbunuh, Ugolino sendiri - bersama dengan anak-anaknya Gaddo dan Uguccione dan cucu-cucunya Nino (julukannya "sang Perampok") dan Anselmuccio ditahan di dalam Muda, sebuah menara milik keluarga Gualandi.
