It lies in walled grounds with mature tree cover, just south of the village core, and is widely hailed as a fine architectural specimen.

[2] Lord Ardilaun's father, Sir Benjamin Lee Guinness, had previously agreed with the parish to build a new church, but the plans did not come to fruition.

[4] The walls are of Wicklow granite, with limestone dressings, and there is a substantial belfry, with Cumberland slates,[1] an octagonal spire and a weathervane.

[2] The Service of Dedication of the church was planned for All Saints' Day 1889 (1 November) but due to a death in the Guinness family was delayed to 16 December 1889.

At about the same time in 1969, the freehold of the land at All Saints was finally purchased from the Howth Estate, for 250 pounds, leaving the way open for full consecration.

[6] Some restoration work was done on stained glass windows in the 2000s, and in April 2010, it was announced that the church required extensive roof repairs and an appeal for a quarter of a million euro was launched[10] while a Government heritage building grant was received in early May.
