Was Sir Christopher Wren a Freemason?

Was St Paul’s Cathedral built by a mason?

With Christopher Wren’s membership of the Craft remaining disputed, Dr James Campbell explains why he chose this subject for his 2011 Prestonian Lecture

Sir Christopher Wren is so well known he hardly needs an introduction. He is England’s most famous architect, the designer of St Paul’s Cathedral. Indeed, up until the age of the railways he was England’s most prolific architect, designing more buildings in his 90 years than any other.

But what makes Wren really fascinating is that he turned to architecture rather late, having already made a considerable name for himself as a mathematician, astronomer and experimental scientist. He was a founding member of the Royal Society and later its president. He carried out the first intravenous injection, was one of the three men who suggested to Newton that gravity obeyed the inverse square law, and was a professor of astronomy at the age of 26. His contemporaries universally described him as startlingly brilliant. Indeed, the more you learn about Wren the more engaging he becomes.

My interest in Wren dates back to 1987, when I first arrived as an undergraduate in Trinity College, Cambridge, and discovered the magnificent library he built there. It sparked a lifelong interest in Wren and another in the architecture of libraries. An interest in Wren served me well and I eventually did my PhD on him and became an architectural historian. One topic kept coming up in my research on Wren: that of his link with Freemasonry. Authors were completely divided on the subject. Many, of course, simply ignored it entirely, but others could not make up their minds whether he was or was not a Freemason, let alone whether it had any effect on his architecture. That uncertainty continues to this day.


If you go on the UGLE website and look at the lists of famous Freemasons, Wren’s name is nowhere to be found. Writers on the subject have also varied in their opinions. John Hamill said in The Craft that the case is ‘unproven’; David Stevenson has said in the past that there is no evidence; while Lisa Jardine, Wren biographer and distinguished historian, is in no doubt that he was. When you look further back – at the eighteenth century – the books of the time all state that Wren had not only been a Freemason, he had been the Grand Master. Some even go so far as to claim that Wren initiated Peter the Great of Russia and William III of England.

The Prestonian Lectures is the only series of lectures officially sanctioned by UGLE. Every year a new lecturer is appointed by the Trustees and announced in Grand Lodge. They choose their own topic. The subject should be suitable for delivery in open lodge or to a wider audience and should be of the broadest possible interest. Wren’s membership of the Craft seemed to me to be ideal and I am pleased that the Trustees agreed.

William Preston (1742-1818), after whom the Prestonian Lectures is named, had been interested in Wren. Preston was convinced Wren was a Freemason and wrote on the subject. He even went as far as buying what he thought was a portrait of him for his lodge. It is now known to be a portrait of the architect William Talman, and it still hangs in Freemasons’ Hall with a plaque wrongly labelled as Wren.

The lectureship Preston founded went into abeyance in the nineteenth century and was revived in its present form in 1924. Since then there have been eighty-two Prestonian Lecturers. Each is entitled to wear a distinctive jewel bearing Preston’s image. In their year of office they give ‘official’ deliveries to lodges chosen by the Board of General Purposes and unofficial deliveries to any lodges that ask for them.

Wren’s membership of the Craft has never been a subject of a Prestonian Lecture before, but is not an infrequent subject of lectures. Most of those I have read are, I am afraid, rather confused.

Most lecturers rely heavily on Robert Freke Gould’s History Of Freemasonry (1883-87), which devotes over fifty pages to demolishing the previously held beliefs that Wren was a Freemason. Few lecturers bother to return to the original sources or look into more recent discoveries. This became my aim: to present clearly how the confusion had arisen and what we now know, and in presenting the evidence to allow the audience to make up their own minds.

Some history is straightforward. Through a series of reliable sources we are able to say unequivocally that something happened on a particular date. Other matters are not so straightforward – vital pieces of evidence are missing or unreliable. This is the case with Wren. The result is a fascinating story of detective work and of shifting views in history.


Wren lived around the time that Freemasonry emerged in the seventeenth century, so the question of his membership also brings up the issue of what Freemasonry was at the time he joined. It therefore provides a fascinating glimpse into the problems we have in studying all parts of early Freemasonry’s history.

Also bound up with this subject is the history of Lodge No. 2, the Lodge of Antiquity, which met near St Paul’s Cathedral. Preston was a member of this lodge in the late eighteenth century and it has a number of artefacts associated with Wren. A lecture on Wren is thus an excuse to go into the history of this wonderful lodge and its origins.

Lastly a lecture on Wren and Freemasonry is an ideal opportunity to ask the question of whether it had any effect on his architecture. Are there any masonic symbols hidden in the works of Wren?

These then were the reasons I chose Wren as the subject of the 2011 Prestonian Lecture and it was a most enjoyable year. I gave lectures all over the UK, and I even went as far as India. One highlight was being asked to give a lecture to the Christopher Wren Lodge in Windsor, which hired the town hall Wren designed for the occasion.

Modernising Wren’s hospital

The proceeds of the Prestonian Lecture and the booklet that accompanies it go to charity. Half of the proceeds from Dr James Campbell’s lecture are going to The Royal Hospital Chelsea. The hospital is undergoing a major restoration and is seeking funds to adapt Wren’s building to modern living. The other charity is the Royal Masonic Trust for Girls and Boys. So far, James has raised more than £6,500 thanks to the generosity of the lodges who have supported the lecture. The sale of the booklet will hopefully raise more. Was Sir Christopher Wren A Mason? contains the complete text of Dr James Campbell’s 2011 Prestonian Lecture and is available from Letchworth’s in Freemasons’ Hall ( for £7.99.
