Ruined chapels are not uncommon in the Irish landscape, but this one sits in a part of Connacht where the post-Famine silence still feels close, and where small ecclesiastical remains can go unremarked for generations, belonging to no particular narrative that history has thought to preserve.

The chapel's origins and the circumstances of its abandonment are not currently documented in any publicly available record, which is itself a kind of fact worth noting. Mayo lost more than a quarter of its population to death and emigration during and after the Famine years of the 1840s, and countless small rural chapels, some of them simple structures of mortared fieldstone with earthen floors, fell out of use as the communities around them contracted or disappeared entirely. Whether Rosslee follows that pattern, or has an older or more particular story, remains unconfirmed. The name Rosslee suggests a placename of Irish origin, though its precise meaning has not been recorded here, and Peenoge itself is a small and unremarkable townland that rarely appears in the broader historical record.
