The belfry of Anini-y church consists of three tiers with a quadrilateral base and the remaining two tiers octagonal and capped with a dome. It is located at the right side of the facade and is attached to the church. It is a simple structure with the details only limited to decorative columns, finials at each corner and dentils along the margin of the tiers and, from afar, looks imposing, looming over the facade. There are windows at each level but not at all sides.
Entrance is via a steel staircase inside the church which is just beside the entrance to the baptistry but seem unstable as it wobbles when one is at the top flight. The original entrance was accessed through the choirloft which is now missing.
The belfry is made from coral stones. This is much evident when one comes up the stairs. There are exposed mamposteria while some surfaces have been covered with cut coral stones including the barrel vault leading to the landing. The window facing the front has been added with a grill
The original wooden staircase is gone except for a piece that is still attached to the wall. Instead, it now has a free standing steel spiral staircase with a cement base leading to the next level where the bells are located.
There are a total of five bells in Anini-y Church, with some, having been recast sometime in 1986 with their esquilas (wooden counterweights for bells that are rotated) scattered at the back of the presybtery.
