Where is "Beachy Head" located?

I thought the rumours about Beachy Head were an Old Wive's Tale until we recently visited. There were leaflets from The Samaritans in the loos and gift shop, also there was an incident while we were there. Very sad and haunting place. However, nearby scenery is spectacular. The little seaside town of Seaford is charming, can watch the ships arriving from France. Eastbourne is lovely, of course!
