The Sultan, who by then was Seyyid Barghash, was so impressed that he donated a large clock; to adorn the bell tower planned for the southwest corner of the structure. Unfortunately there was no clock in the original plans.
Mfalme ambae kwa wakati huo alikuwa Seyyid Barghash alivutiwa sana na aliamua kutoa saa kubwa, ili kuupamba mnara wa kengele ambao uliwekwa pembe ya kusini magharibi ya jengo.
