Images of Wooden Horizontal Square-Bin Grain Elevators through history and across the continent. (Diagnostics are in a separate webpage.)
Grain Elevators are ubiquitous buildings, yet there is little popular understanding of them and their origins.
The basic arrangement of a grain elevator fits into two different "Type Families" based on whether it is a discrete building ("Self-Contained"), or a semi-dispersed cluster of structures (Annex).
Within those classifications, there are several distinctive types based on grain bin design and arrangment. Construction material and assembly then determine different subtypes or material variants.
An index to this and related typologies spells out the interrelationships concisely (without the clutter of images and descriptive text). Related and similar building and structure types are in a sibling websection.

This lacks a cupola, and may not even be a grain elevator. It was labled "Mid-Ohio Fertilzer & Pesticides," so there may not be any grain involved. But, this was beside an abandoned railroad, and has a grain auger running up to its roof ridge.
