I started Open Plaques in 2009 as a way of quickly showing London’s blue plaques on a map.
I soon discovered that there are plenty of plaques in places other than London, and they’re not even all blue.
The site was developed at a Yahoo Hack Day in London, where I teamed up with a few other developers to add new features and data.
Unlike most hacks, development has continued ever since, with more and more people getting involved with the site.
The data on the site is all Public Domain, and there have been numerous hacks, apps and even books produced off the back of it.
Along with the other contributors, I established a non-profit organisation, Open Heritage C.I.C. to host and manage the site. We have also successfully applied for small grants to fund development.
