Grand Theatre

This list of Rock Falls businesses in the year 1913 lists 311 W. 2nd Street as the location of The Grand. As it doesn’t specify theater, this might have been a multi-purpose hall, perhaps with a flat floor so it could be used for dances and such, as well as movies and other entertainments. The next year available in the series, 1920 (hover your cursor over “Businesses” in the header) lists 311 as the location of “Buckingham A soft drinks,” so the Grand must have been gone by then.
