What did Gas Light & Coke Company green plaque do at Great Peter Street / St Anne's Street junction?

The Story

# Gas Light & Coke Company Standing at the junction of Great Peter Street and St Anne's Street in Westminster, you're positioned at the birthplace of modern urban illumination. From 1813, the Gas Light & Coke Company operated a pioneering gasworks at this very spot, establishing the world's first public gas supply system and fundamentally transforming how cities were lit and powered. Here, beneath London's streets, engineers and workers produced gas that would flow through revolutionary underground mains to light the homes and streets of the capital, replacing the dimness of candles and oil lamps with reliable, manageable flame. For 124 years, until the gasworks closed in 1937, this unassuming corner of Westminster remained the technological heart of a quiet revolution—a place where practical engineering met public ambition, and where the gas that lit Georgian, Victorian, and Edwardian London was born.
