An amusement park based on horses, doesn't sound like something that would last. It didn't. However to an eccentric millionaire named Thomas Smrt, it sounded like a grand plan. It is unclear how long Shireland was open, but it seems like 1988-1990 was about it.
Shireland had some permanent structures, but it was mostly made up of huge red and white tents. Below are description of various attractions at Shireland.
