[2]: p.131 In 1630, the archiepiscopal visitation reported that the church was ruined, only bare walls remaining, and there were no Protestants in the parish, although there was still an assigned curate - and the tenant still collected tithes, while also allowing Roman Catholic Mass to be said in his house.

[2]: p.131 Renewal of the lease of the Grange was sought in 1630 and granted by Dublin Corporation in 1638, for seventy years at 240 pounds per annum, but there is no mention of any repair to the chapel, and in 1675, the curacy of Baldoyle was merged into the parish of Howth.

[2]: p.131  The chapel is mentioned again from the early to mid-19th century, as a picturesque ruin, abandoned (and without tithes), on the grounds of Grange Lodge, Baldoyle, the whole civil parish still being the property of Dublin Corporation, generating an annual rental of 4,790 pounds.

[2]: p.132 Development of municipal property in the lands surrounding the abbey began in the late 1960s, with the construction of modern roads and corporation housing,[2]: p.129  but the church building was protected and has been the subject of a formal preservation order since 1981.
