Thomas Clarkson monument

The Thomas Clarkson monument sits in Hertford, honouring the man who became the driving force behind the abolition of slavery across the British Empire. It's a straightforward tribute - a statue and associated information that tells you exactly who he was and why he mattered. Clarkson spent his life campaigning, and this memorial doesn't shy away from that graft.

History buffs will find it genuinely worthwhile, particularly those interested in the Georgian era and the abolition movement. The monument itself is modest rather than grand, which somehow makes it more powerful. You won't need more than twenty minutes here, though the surrounding Hertford town centre rewards a proper wander - there's medieval architecture and decent cafes nearby.

It's free to visit, which is exactly how it should be. The best time is a quieter weekday morning when you can actually think about what you're looking at without crowds. Families with older children keen on British history will get something from it; younger kids might find it a bit static.

If you're basing yourself at one of the nearby parks - Toad Abode or Hertford Camping and Caravanning Club Site are both highly rated and within easy reach - the monument makes a logical addition to a morning exploring Hertford's Georgian character. Combine it with the castle grounds and you've got a solid half-day. It's not a showstopper attraction, but it's worth your time if you're in the area.
