The architectural historian William Aslet invites us to look up and look around us at this glorious 300-year-old building. James Gibbs was one of the most important architects in eighteenth-century England, bridging the Italian Baroque and English Palladianism. His buildings include the Radcliffe Camera in Oxford and the Senate House in Cambridge, many spectacular houses, and the churches of St Mary-le-Strand and
St Martin-in-the-Fields.
