Sir Christopher Wren casts the longest shadow of all English architects, still reaching into our own times, the 25th of February 2023 marks 300 years since his death. It can sometimes feel like everything built after him is in some way a response to or repudiation of his astonishing legacy of construction. From the Sheldonian Theatre in Oxford, through a diverse set of city churches, military hospitals and college libraries, and on to his undoubted masterwork, St Paul’s Cathedral, Wren’s architectural career was as varied as the styles in which he worked. His habit of dancing between Palladianism, pure classical revival, ornamented Baroque, and even the Gothic vernacular, has left many students of his architecture desperate for a unifying factor, something that can collect each work into a comprehensible retrospective. Instead of adding to the flutter of articles and essays exploring Wren’s buildings that will mark this anniversary, I’m going to explore the fragmentary and limited texts that Wren left behind which may give us a clearer idea of the great man’s own personal explanation of his career.
