I’ve lived in Billings for 8 years now and have been hearing about the Moss Mansion. I’ve been told several times, but various people that Moss Mansion was beautiful inside and that I needed to check it out. For some reason, I just never was that enthused about it. I finally checked it out last weekend and whoa. I have to emphatically insist that if you are at all into history, design or architecture, that you NEED to take this tour. It’s self guided, so you can go at your own pace. I was told that everything inside is 90% original to the home; they’ve had to restore some things but for the most part, it’s all original. I was just blow away. I highly recommend this tour.
