“Fascinating!! I had no idea there was so much science involved. The historic context and techniques were beautifully explained and made for a remarkable lunch. Thank you so much for such a fantastic opportunity to learn.”

Explore London with us! We take our Patrons to studios and workshops around the city, and on special visits to get up close to projects and find out the research behind them. We ask you what you’re interested in and how often you can meet.


Patrons join us for lunches and dinners throughout the year. It’s a great chance to meet other Patrons and support our work at the same time.


“The work HOLT does is unrivalled and if you have the same passion for London’s heritage as I do or even if you have a fraction of the passion that I do, you could get some serious enjoyment from being part of the Trust.”


  • Edward Benyon, Chairman of the Patrons’ Committee
