We want to see as many Hertfordshire county flags flying, running up to, and on July 23rd!
Use the hashtag #CountyFlagsDay on your photo on Twitter, Facebook or Instagram. Alternatively you can email us your picture to countyflagsday@abcounties.com.
For the history and background of the Hertfordshire county flag, please see the Hertfordshire Flag section on the British County Flags Blog.
Colour in Hertfordshire!
