In 1973, Gary Gygax and Don Kaye founded the firm TSR -- Tactical Strategic Rules. The next year, this company created Dungeons & Dragons.
This cultural phenomenon had humble origins. Those origins include a hobby shop named the Dungeon Hobby Shop which Gygax established in 1976 at 723 Williams Street in Lake Geneva, Wisconsin. TSR went through varied fortunes before Wizards of the Coast purchased the company in 1997. So did the hobby shop, which eventually became a museum about Dungeons & Dragons. It closed several months ago.
Now the building is for sale. You can see more photos of this magnificent historical landmark at the realtor's website.
