Minute man silos (by Craftsman 2001)
In England I had a pick of thousands of silos from farms across the country before settling on these with a brickwork base. They look older that those in made of concrete or steel.

In Germany I discovered a factory at Erfurt which makes feed for cattle, pigs and chickens. The picture dates from 1977 when they made 2000 tons more of the stuff than in 1976.

My first project as a graduate trainee in the steel industry in the UK was to make up trial sinter mixes for the blast furnaces at Redbourne Works in Scunthorpe. We did it the hard way with a shovel!
When I found this picture of the charging hoppers (silos de chargement) for a blast furnace in France it just had to be included.
How many of you remember the Gregorian Chant sung in by monks from the monastery of Santa Domingo de Silos. They made the UK charts in the 1990s. The monastery is located in Northern Spain.
I could have picked many images from there but settled for one from their laboratories, If you use your imagination you can scale up the vessels to 'silo' size and anyway it's the nearest I could get to a sepia colour.
Finally to Norway where I worked on the early stages of the project to build the Troll A gas platform.
This tilting concrete tower in Jåttåvågen is 60m tall at Hinna, in Stavanger. The tower which is tilting 16 degrees towards the ocean was originally built in 1984 for experimental tests before they started on the Troll-Platforms in the later 1980s and 1990s.

Troll-A Platform at 472m tall, was the tallest and heaviest construction ever moved by man). The legs of the platform go down over 300 metres; 100 meters at the bottom are tilted like the tower in the previous picture.
