The belfry of Oslob church is imposing owing to its size relative to the facade. It was constructed during the time of Fray Mauricio Alvarez (1866-1881). Originally a 5 level structure, the topmost level was destroyed by a very strong typhoon during the time of Fray Gregorio de Santiago (1892-1898). Most of the bells, including the biggest one fell to the ground and cracked. Instead of restoring the topmost level, it was left as it is and the fourth level was just covered.

The belfry has 11 bells put mostly in place by Fray Alvarez and, according to Agustin Villalon, has the most number of bells of any colonial era church in the country. The earliest bell was cast 1825 and still bears the name of Boljoon of which Oslob was still a visita then.
