Visited this site with a friend and had fun getting inside 
I missed quite a few areas I think but had a good couple hours wandering and chilling on the roof,
Secca are not on site but they did come along while we were there and seemed to hang around for ages.
Millennium Mills was designed and built by millers William Vernon & Sons of West Float, Birkenhead in 1905 with construction overseen by W. A. Vernon, the principal's son. The mills were extensive, featuring two plants, equipped by Henry Simon Ltd, that had a capacity of 100 sacks per hour. W. A. Vernon described the mills in a single word as "palatial". Vernon and Sons named the mill after their most successful product, a flour variety which they called "Millennium Flour" after winning the "The Miller Challenge Cup" at the 1899 International Bakers Exhibition. The flour had been selected from "the best wheats of the world" and was put through a carefully designed industrial process. The victory gained Vernon and Sons "world-wide fame" and dominance in the English flour market. Millennium Flour was aimed at the rising 20th-century masses, proving particularly popular in the mining districts, where it was known to make "beautiful white bread sandwiches". The erection of Millennium Mills at the Royal Victoria Dock meant that this new flour could be brought to the Southern England market.
