[3] The church appears to have been largely rebuilt to a Georgian style under the direction of architect Michael Wills from 1750-52.

For a number of years, he managed to raise over £4,000 per annum for charity, in addition to donations of jewellery, watches and other items which parishioners overcome with emotion spontaneously threw into the collection plate.

[7] After the church was closed the churchyard was taken over by W & R Jacob's biscuit factory as a recreation ground for its staff.

In December 2000 planning permission was granted to the YMCA by Dublin Corporation to erect a hostel at the site.

Among the notable people buried in St. Peter's Churchyard were the Earl of Roden and several members of his family, along with a great number of bishops and other dignitaries.

Also interred there are the Dunboyne family, the judge Charles Burton, Mary Anne Holmes, and the notorious Black Jack Fitzgibbon, Earl of Clare and Lord High Chancellor of Ireland.

Notable parishioners associated with St. Peter's when the church was built in the 17th century were the Cuffe family (after whom Cuffe Street is named), who were relatives of the Aungiers, Lord Arran (son of the Duke of Ormonde), Lady Antrim and Lord Merrion[9] and Lieutenant-general Archibald Hamilton, who fought at the Siege of Derry, in 1688.

According to this story, which was independently shared by the Hammond family, friends of the Emmets, the interment of Mary Anne Holmes around 1804 was used to secretly transfer Emmet's body from St. Michan's Church with the help of the Rev Thomas Gamble, who ministered in St Michan's.

Catherine, daughter of Owen Connellan, writer, antiquarian and Professor of Celtic Languages and Literature at Cork, who had a house in Emor Street, was married in the church.
