Should the two historic “Frankenstein mansions” on Franklin and East Colfax – badly damaged by a fire following years of neglect — be demolished or should Denver’s preservationists prevail in their demands the homes be restored to their former glory? The truth is that little remains architecturally on the 130-year-old buildings worth salvaging, and that was the case even before the Wyman Historic District was designated in 1993 to save a neighborhood full of stately mansions of historic value.
