If you’re one of those people who laments the lack of variety in British high streets these days, a display in the newly re-opened North Hertfordshire Museum may interest you. It’s a reconstruction of part of Parks and Llewelyn, a pharmacy which stood on Hitchin’s high street for over 170 years till its closure in 1961.

The most diverting item isn’t the various bottles with their mysterious potions and remedies, but what hangs above them; the jawbone of an alligator. This is a reference to the stuffed crocodiles which used to adorn the entrances to apothecaries’ shops in medieval times.

We said hello to the jawbone as part of a visit to the Museum on the occasion of its re-opening, on Saturday 6 July. It’s been partially open for a while, but a dispute over land ownership meant that, for some years, only pre-booked tours were available and visitors had to go in via the Town hall entrance next door.

Happily, that problem was consigned to the past by the opening ceremony. It featured children from Samuel Lucas JMI School reciting what their teacher called a rap – there was no music, so it was in reality a poem – about the eponymous Lucas, a 19th-century brewer and artist who lived and died in Hitchin. After the ceremonial cutting of a red ribbon, the children, their teachers, parents and other visitors streamed inside to explore the new facilities.

The ‘Discovering North Hertfordshire’ gallery on the ground floor covers local history from 90 million years ago to the present day. Sadly, the fibre glass reconstruction of the head of a parasaurolophus – a duck-billed dinosaur – is no longer on display, but there is still plenty to inform, entertain and surprise.

The other main element of the ground floor is a temporary exhibition space, currently used for ‘Blood and Bone’, an interactive installation of inflatable sculptures inspired by cells and organisms from inside the human body. Plenty of children enjoyed themselves, crawling in and out of the installations, as the adults refreshed themselves with drinks from the new onsite café.

The other principal new features are on the second floor (the first floor is reserved for staff office space). ‘Living in North Hertfordshire’ explores how people have lived, worked and died in the region, and features local characters and industries, as well as examples of what people used to wear and the toys with which children used to play. Look out for an exquisite Spitalfields silk dress and quilted petticoat from the early 18th century, and a slightly spooky Japanese doll. The adjacent Terrace Gallery gives you the chance to dress as a suffragette (and commendably explains the difference between suffragists and suffragettes) and showcases various other items, including a selection of ephemera from a football-related collection. The Arches Gallery, part of the Terrace Gallery, is currently showing a collection of work by Vanessa Stone, a local artist.

The Terrace itself is not yet in use, but no doubt this will change in due course. In the meantime it’s good to see the Museum fully open, and it looks set to become a very popular local attraction for years to come.
