Since 1901
The room does the talking
This building went up in 1901 and the bar has been in it ever since. The back bar is the original. So is the pressed tin ceiling over your head.
Not restored to look old. Just never torn out.
Red Lodge has changed around it for more than a century. The Snag has mostly just stayed put — which is why it turns up in a Montana preservation writeup, and why people who find it tend to come back.
