It became the largest hot-strip steel mill in western Europe and at its peak had 13,000 workers.
In 1967, the industry was nationalised and British Steel took over the running of Ravenscraig.
Despite the plant repeatedly breaking steel industry production records, its future looked bleak as early as 1979 and the national steel strike.
Around 700 jobs were shed in the early 1980s and severe cuts continued throughout the decade.
In the plant's final two years, 1990-1992, more than 4000 steelworkers were made redundant.
On Saturday, June 27, 1992, Ravenscraig officially closed and the last 800 workers lost their jobs.
Construction of Ravenscraig, one of Scotland's most ambitious regeneration projects, is continuing on the brownfield site.
