London Coal Duty Marker, Coursers Road, Colney Heath, Hertfordshire
This London coal duty marker was built in 1861-2. It marks the limit of coal duty in the London area. This is the boundary at which duty (tax) was payable on coal and wine. If you passed the post you had to pay the tax. The tax on coal dates back to the 1660s. This is one of four in this parish and is a very well preserved example, probably the best in Hertfordshire.
