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!
