SHOSHONE, Idaho — One of the oldest buildings in Shoshone, one of southern Idaho's oldest towns, has been torn down. The historic Animal House — a structure dating to the late 1800s or early 1900s — was demolished after years of attempts to save it. The city of Shoshone and the building's owner agreed that demolition was the best path forward. Shoshone Mayor Dan Pierson said it was a difficult decision for the historic railroad town, which was founded in 1882.
