Winchester Science Centre — INTECH until 2013 — is at Morn Hill near Chilcomb, five kilometres east of the city, and it takes over 185,000 visitors a year.

It is a hands-on science and technology centre with an attached planetarium, and its stated core audience is children aged five to twelve. That is worth taking literally.

The planetarium

The dome seats 176 and it is the largest standalone planetarium in the UK.

Shows run through the day on a schedule: astronomy presentations, children’s shows, and live-narrated sessions on the current night sky. They are included in the admission, though popular sessions may need a slot booked on arrival.

The dome is the reason a visit here is different from a general children’s activity centre, and it is the part adults consistently rate highest.

Evening astronomy events and observing sessions run through the darker months, and are worth checking.

The exhibits

Over a hundred hands-on exhibits across a large hall, covering forces, light, sound, electricity, the body, engineering and space.

Live demonstrations and science shows run through the day, with liquid nitrogen, electricity and the usual reliable spectacle. Visitors specifically praise these — the shows are where the science actually gets explained.

Recent additions include an outdoor dinosaur dig area and a chalk stream exhibit, both well received and both accessible to younger children.

Outdoor space and a play area.

An honest note for adults

It is a children’s centre.

Adults visiting because they are interested in science, without children, consistently report the same thing: the exhibits are pitched young, and the environment is loud, fast and full of children moving between exhibits rapidly rather than working through them.

That is not a fault. It is what the place is for, and it does it well. But an adult expecting a Science Museum experience will not get one.

Go with children, or go for a planetarium show or an evening astronomy event, which are pitched differently.

The annual pass

The Curiosity Pass converts a single admission into a year’s unlimited return, and it is heavily used by local families — some of whom report seven or eight visits in twelve months.

If you are within reach of Winchester and have children in the right age band, it is much the best way to buy.

Practicalities

Admission charged; the annual pass is excellent value for repeat visits.

Time: three to five hours with shows; a full day if you use everything.

Facilities: café, picnic areas, shop, toilets.

Parking: free on site.

Access: the building is level and accessible throughout, including the planetarium.

Weather: almost entirely indoors, which makes it a first-choice wet-day option for the region — and correspondingly busy when it rains.

Booking: advisable in school holidays.

Getting there

Telegraph Way, Morn Hill, off the A31 east of Winchester — about ten minutes by road, signposted, with free parking.

Around it

Winchester city centre is ten minutes back west.

St Catherine’s Hill and the water meadows are on the other side of the city.

Old Winchester Hill, the Iron Age hillfort in the South Downs, is twenty-five minutes east.
