This was a project initiated by this Civic Association and inspired by blue plaques which can be found elsewhere in the UK.
Green Plaques 
Many familiar with the blue plaques scheme may be surprised to know that they started as long ago as 1866 in London and are thought to be the oldest kind of commemorative plaques.
London’s famous blue plaques link people of the past with the buildings of the present. You can find out more about the plaques by searching online for WEnglish heritage blue plaques’.
Outside London, many councils, civic societies and other organisations run similar plaque schemes. However, all sorts of commemorative plaques have emerged over the years. These range in both colour and also content, which has expanded beyond the original concept of linking notable people with a building.
You can find information about these plaques on a couple of websites, which include plaques which have been installed in Wales: blueplaqueplaces.co.uk/ and openplaques.org/places/gb. (Sadly no-one has picked up on the ones in Ruthin. We shall provide this information to the appropriate organisations to remedy this!)
In 2005, members of the Civic Association with financial support from Ruthin Town Council and Cadwyn Clwyd researched and installed 14 plaques in Ruthin. The aim was to provide both residents and visitors to Ruthin an interesting fact or two about the various historic buildings in the town. In the following year, five additional plaques were put up, which included Rose Cottage and Crown House. The last plaque erected in 2014, which brought the current total to 20, was the plaque to commemorate the native artist Edward Pugh – following research which Professor John Barrell had carried out about the artist’s work in Cambria Depicta.
We have now created a map and numbered trail of the locations of the Green Plaques. Photographs of the Green Plaque locations will be on display in Ruthin Library during August and September. Free copies of the map-and-list of locations will also be available so you can follow the trail around the town. An ideal activity for children (and adults!) to do during the summer holiday and Open Doors.
