Rotten Row in Hyde Park, popular for horse riding with the gentry. Rotten Row was established by William III at the end of the 17th century. Having moved court to Kensington Palace, William wanted a safer way to travel to St. James's Palace. He created the broad avenue through Hyde Park, lit with 300 oil lamps in 1690– the first artificially lit highway in Britain. The lighting was a precaution against highwaymen, who lurked in Hyde Park at the time. The track was called Route du Roi, French for King's Road, which was eventually corrupted into "Rotten Row".
