Northamptonshire Day is observed in Northamptonshire, England, every October 25, coinciding with the feast day of Saints Crispin and Crispinian, the patron saints of shoemakers. This celebration honors the county's historical significance as a major center for shoemaking and the leather industry, particularly during the 19th century. The day features flag-raising ceremonies across the county, showcasing the official maroon banner with a gold cross and a rose, symbols of Northamptonshire's heritage. BBC Radio Northampton also hosts festivities about a month earlier, including markets with local producers, guided tours, music concerts, and contests. The first mention of Northamptonshire dates back to 1011 in the Anglo-Saxon Chronicle, and the county has evolved from an agricultural area to a key industrial hub. The local community embraces the legacy of Saints Crispin and Crispinian, who are celebrated for their faith and craftsmanship.
