Unfortunately, if you use our postcode your GPS will probably direct you to a CLOSED entrance of the Herstmonceux Castle Estate (600 acres). This will result in a 10 minute re-route.

The correct entrance is at the junction of Wartling Road and Halley Road (Private road within the estate).

Co-ordinates for the CORRECT entrance from Wartling Road have been pre-programmed into the Google location map on this web site.

The Co-ordinates are:
50.8685865,0.348961




How to find us

The Observatory Science Centre is within the Herstmonceux Castle Estate in East Sussex. It is 2 miles east of the village of Herstmonceux on the Boreham Street to Pevensey Road, near Wartling.

Look for brown directional tourist signs to 'Herstmonceux Castle and Science Centre'. 

Sadly there is a shortage of these signs and the Highways Agency does not permit any more to be added.  As you near The Centre, if you can spot the green, copper clad domes - or the grey, steel Isaac Newton Dome, then you are almost there!

From the north:
The most direct route is to continue south on the A22 to the large Cophall Roundabout at Polegate, just north of Eastbourne, then proceed as below (from the west).

From the west:
Travel along the A27 to Polegate, then at the Cophall Roundabout follow the A22 / A27 eastbound to Pevensey. At the Pevensey Roundabout, take the 1st exit on the left and follow the sign for Herstmonceux Castle, 3 miles along the Wartling Road.

From the east:
Travel along the A259 to the Pevensey Roundabout. Take the 4th exit and follow the sign for Herstmonceux Castle, 3 miles along the Wartling Road.

Cyclists can travel across the picturesque Pevensey Levels from Pevensey railway station. The route is very flat with only 1 hill at Wartling - journey time varies from 25 - 45 minutes depending on pedal power and wind direction!

The Observatory was intentionally built in the middle of the countryside, away from light pollution, and cannot be readily accessed by public transport.

The nearest mainline train station is Polegate where taxis are always available. The nearest main buses will stop in Hailsham and a taxi is then required.

Cuckmere Community Bus 2016

Leave the car at home!

We are delighted to announce that Service 49 will be operating every Wednesday from 17th February 2016

This service links The Observatory Science Centre to Pevensey and Eastbourne via the Seafront, Langney Shops, Westham and Wartling.

The bus will drop off / pick up immediately outside the reception to The Centre and enables visitors without their own transport to visit this fantastic attraction.

PLUS! If you present a valid Cuckmere Community Bus ticket (same day only) at reception you will be entitled to a reduced admission of just £5 pp.

Cuckmere Community Bus 2012

In 2012 we were delighted team up with The Cuckmere Community Bus to trial a circular service from Polegate railway station with the times of the bus service planned to link with train arrivals at Polegate station.

This service was made possible through a grant from East Sussex County Council under the Community Transport Development Fund provided by the Department for Transport. Being a circulor route it linked a wide rural area with a mainline railway station and was supported by many people - not just those wishing to visit The Centre.
