Can Anyone Identify Bangor Church from 1916 Painting?

My grandfather, George Kelly, emigrated to the United States from Bangor, Ireland in 1916 at the age of 41.

A friend in Bangor painted a picture of the church that my grandfather attended in Bangor.

A photo of the picture is attached.

Might anyone be able to identify the church?

The church looks quite old in the painting, and the painting is from 1916 or earlier, so the church, if still standing, would presumptively be quite old.
