About the 5th bell: The name ''Pasquareccia'' comes from ''Easter'', because it used to ring on Easter day. However, this bell is older than the bell-chamber itself, and comes from the tower Vergata in ''Palazzo Pretorio'' in Pisa, where it was called ''La Giustizia'' (The Justice). The bell was tolled to announce executions of criminals and traitors, including [[Ugolino della Gherardesca|Count Ugolino]] in 1289.<ref name="Ugolino">{{cite web |url=http://www.luccaturismo.com/umutesiadd.asp?id=56 |title=Torre pendente |access-date=19 March 2008 |publisher=Lucca turismo |language=it |archive-date=8 April 2008 |archive-url=https://web.archive.org/web/20080408070258/http://www.luccaturismo.com/umutesiadd.asp?id=56 |url-status=live }}</ref> A new bell was installed in the bell tower at the end of the 18th century to replace the broken ''Pasquareccia''.{{Citation needed|date=August 2019}}

The circular shape and great height <!-- (currently {{convert|55.86|m|ftin|2|abbr=on}} on the lowest side and {{convert|56.67|m|ftin|2|abbr=on}} m on the highest) -->of the campanile were unusual for their time, and the crowning belfry is stylistically distinct from the rest of the construction. This belfry incorporates a {{convert|14|cm|in|frac=2|abbr=on}} correction for the inclined axis below. The siting of the campanile within the Piazza del Duomo diverges from the axial alignment of the cathedral and baptistery of the Piazza del Duomo.{{Citation needed|date=August 2019}}
