View the list of Blue Plaques in Horncastle and use with our Town Walk leaflet. Learn more about our rich heritage and famous people.
The Society are responsible for the selection and production of the Blue Plaques in Horncastle, with funding assistance from the Town Council.
We suggest that you use the following list and the Horncastle Town Walk leaflet we devised, with Lincolnshire County Council, to appreciate the attraction of our ancient market town. The plaques are in the order they appear when using the Walk leaflet. The only plaque you will not see during the walk, unless you deviate through the Wong, is the Drill Hall on Boston Road.
Do you have an idea for a new blue plaque? Let us know at the Contact Us page on this website.

More blue plaques have since been erected:

16. At 40 East Street, to mark the work of Annie Dixon , one of the most famous miniature portrait artists of the Victorian period and a particular favourite of Queen Victoria herself. This was the first plaque in the town to honour a woman.
