Foyle has written many scholarly papers and additionally contributed articles for a number of newspapers and popular magazines.
He is perhaps best known as a passionate communicator on history. He has taught and lectured widely in Britain and around the world and has appeared and presented a number of television broadcasts.
Since 2002, he has presented films for Channel 4, the BBC, the History Channel, ITN, Lion and Discovery Channels. His 2009 series on Henry VIII as art patron garnered praise. In 2010 his television series Climbing Great Buildings captured his largest audience yet. He delights in working without a net, whether by dangling from an immense height in order to comment on the iron tracery of St Pancras railway station or by improvising a pencil sketch of the pyramids' surroundings in Egypt.
In 2007 Foyle accepted the position of Chief Executive of World Monuments Fund Britain, the UK arm of a global charity, which has achieved great success in securing imperilled architectural sites for future generations.
