How to get here
GPS users please DO NOT use our postcode in your GPS as this will take you to the closed back entrance of the Herstmonceux Castle Estate and will result in a 15 minute re-route. The correct front entrance is at the junction of Wartling Road and Halley Road (Private)

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 the brown signs to 'Herstmonceux Castle and Science Centre'.

There is a shortage of these brown directional tourist signs and unfortunately the Highways Agency does not permit us to add any more. 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 it is now more direct to continue south on the A22 to the large roundabout north of Eastbourne, then proceed as below.

From the west travel along the A27 to Polegate, then follow the A22 / A27 eastbound to Pevensey. At the ‘Esso’ roundabout, take the 1st exit and follow the sign for Herstmonceux Castle, 3 miles along the Wartling Road

From the east travel along the A259 to the ‘Esso’ roundabout at Pevensey. 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!
