Idaho has some incredible, beautiful, and historic buildings that are always worth checking out. But, tucked away in one of northern Idaho’s state parks is the oldest building in the Gem State — Mission of the Sacred Heart. Dating back to the 1850s, this church is still standing tall and just as beautiful and remarkable as it was decades ago. Today, you can visit this breathtaking structure, get a glimpse into the past, and receive an educational experience like nowhere else in Idaho. The oldest building in Idaho is one destination that I strongly recommend you place on your bucket list.

Coeur d’Alene’s Old Mission State Park is one of the most unique state parks in Idaho. Located in Cataldo, in northern Idaho, it is the perfect day trip destination.
