The exhibit shows how humans domesticated the horse and includes a timeline on how their relationships with humans evolved.
The exhibit runs through August 14.
Visitors can explore more than 200 breeds and learn why horses can stand all day without becoming fatigued.
Items on display include a full suit of armor from 15th century Germany and a 19th century horse-drawn fire engine. There's also a life-size, interactive video looking inside a horse, fossils, and hands-on activities, too.
