The chapel was built between 1541 and 1544 using money bequeathed by Michael MacQueen, supplemented by his widow, Janet Rynd. The Foundation Charter of 1547 reads: 'when the said Michael was greatly troubled with an heavy Disease, and oppressed with Age, yet mindful of Eternal Life, he esteemed it ane good Way to obtain Eternal Life, to erect some Christian Work, for ever to remain and endure.' It was designed to accommodate a chaplain and act as an almshouse for seven poor men who were to pray for the soul of Mary, Queen of Scots. Prior to the Reformation, the Queen Regent, Mary of Guise arranged academic lectures there. Patronage of the chapel passed to the Incorporation of Hammermen on the death of Janet Rhynd in 1553. After the Reformation, the patrons – the Hammermen – met financial trouble. The chaplain, who remained a Roman Catholic, was replaced by a Protestant minister, but successfully sued to continue to receive his salary until his death in 1567. Under the terms of the Foundation Charter, the Chapel was required to undertake Roman Catholic worship and the Hammermen were prohibited from doing anything against Roman Catholic interests or the property would revert to Janet Rynd's heirs. Since these terms were now breached, the tenants stopped paying their rent, knowing the Hammermen could not force them to pay. Only the wealth of the Hammermen allowed them to continue as patrons. From 1596 it was also the regular meeting place of the Convenery of the Trades of Edinburgh. The meeting-place was so closely identified with the Convenery of Trades that ‘Magdalen Chapel’ was often used as a metonym for the Convenery itself. The General Assembly of the Church of Scotland was held in the Chapel in April 1578. There is a tradition that the first General Assembly in December 1560 was also held in the Chapel. Several conventicles of the Covenanters were held in the Chapel, the largest being that of May 1674 at which William Weir was the preacher. The bodies of the Marquis of Argyle in 1661, Hew Mackail in 1666, and John Dick in 1684 were prepared for burial in the chapel after they were executed. The heads and hands of martyred Covenanters were displayed in various locations in Edinburgh in 1689, and were collected at the chapel prior to burial in Greyfriars Kirk. The Chapel was used by Episcopalians, and by a Baptist congregation in the 18th century. A printing press was located either in the Chapel or a nearby building in the 18th century. In the early nineteenth century it was used as a place of worship by the Bereans, a Protestant sect following former Scottish Presbyterian ministerJohn Barclay who held to a modified form of Calvinism. The Hammermen sold the chapel in 1857 to the Protestant Institute for Scotland, and it was used by the Edinburgh Medical Missionary Society. Architects Simpson and Brown undertook a major restoration programme in 1992/93. It is now the headquarters of the Scottish Reformation Society.

An inscription over the door reads 'He that hath pity upon the poore lendeth unto the Lord and the Lord will recompence him that which he hath given, Pro. XIX vers XVII.' A semi-circular wooden platform was installed at the east end around 1615 and the layout of the Chapel was altered. The carved armorial panel over the door was created by John Sawer in the same year, and was moved to its current location in 1649. The tower and spire were added about 1620. A bell, by the Dutch bell founder Michael Burgerhuys of Middelburg, dates from 1632. The original ceiling, no longer extant, was painted in 1725 by Alexander Boswall in 'skye colour with clouds and a sin gilded in the centre'. ' A fragment is on display on the south wall. The panelling records gifts from members of the Incorporation of Hammermen. The stained glass in the middle window of the south wall features the Royal Arms of Scotland and the Arms of Mary of Guise. It is the only intact pre-Reformation stained glass window in Scotland. A sword that reputedly belonged to the Covenanter Captain John Paton and the table used to prepare the bodies of the Covenanters for burial are still present in the chapel. Janet Rynd's tomb, with her coat of arms and an inscribed border, is in the south east of the church.
