Church of the Assumption, Booterstown, Catholic church in Booterstown, Ireland

The Church of the Assumption is a Roman Catholic church in Booterstown, County Dublin. Its foundation stone was laid on 6 August 1812, and Richard FitzWilliam, 7th Viscount FitzWilliam, paid for the building, instructing the architect to make it look like a house rather than a church. It was dedicated to the Feast of the Assumption on 15 August 1813 by Dr. John Troy, Archbishop of Dublin.

The parish was established in 1616, with a boundary running from Irishtown through Donnybrook, Rathfarnham and Sandyford to Seapoint. The foundation stone of the present church was laid on 6 August 1812 at the expense of Richard FitzWilliam, 7th Viscount FitzWilliam, and it was dedicated on 15 August 1813 by Dr. John Troy, Archbishop of Dublin. In 1872 a new presbytery and a school for the Sisters of Mercy were built at a cost of £4,400.

The parish takes its name from the Feast of the Assumption, to which the church was dedicated on 15 August 1813 by Archbishop John Troy. The parish itself was established in 1616, and its original boundary ran from Irishtown through Donnybrook, Rathfarnham and Sandyford to Seapoint. Donnybrook (1747), Dundrum (1879), Blackrock (1922), Mount Merrion (1948), Merrion Road (1964) and Newtownpark (1967) were later separated from it.

The building is easy to reach and visible from the street, with a clear entrance for visitors. It is worth visiting during the day to experience the church activities and local community.

The building was intentionally designed to look like a private house to remain inconspicuous in the neighborhood and avoid conflict. This unusual choice makes it difficult for visitors today to recognize it as a place of worship.
