Thorns of Harpenden is the oldest shop in the town. The shop front proudly displays its founding date of 1918. Step inside and it’s as if time has stood still. The original cash register and weighing scales sit behind the counter and on display is an assortment of sweets of which Willy Wonka would be proud. It is also one of the few places that still sell loose tobacco in the area and has a wall display of pipes.
