The famous sign, which was erected in 1923, originally read "HOLLYWOODLAND". It was studded with around 4,000 light bulbs and flashed in segments, with "HOLLY," "WOOD," and "LAND" lighting up individually, and then as a whole.

But by the time it came out in the press it sounded like we were wearing a bucket of blood around our necks."

Scientology operates eight locations that are designated Celebrity Centres, designed to minister to celebrity Scientologists. The first of these opened in Hollywood, California in 1969.
