Carl's Ice Cream is a curbside ice cream stand located at 2200 Princess Anne Street, Fredericksburg, Virginia. Since 2005, the stand, with its Art Moderne architectural facade, has been listed on the National Register of Historic Places.HistoryCarl Sponseller founded Carl's Frozen Custard stand in 1947. The original building was registered as a National Landmark and is an official register of Historic Places in 2005. Since 1947, the 1940s era Electro Freeze machines have produced the frozen custard daily. Custard is different from ice cream because it contains eggs, and sells only three flavors, Vanilla, Chocolate, and Strawberry. When Carl retired he passed it to his brothers, Paul Sponseller and Herbert Sponseller. When they in turn retired it was passed to Ramona Sponseller (Settle), Daniel Sponseller, and Cristina Sponseller (McCann); keeping it in the family. The stand has what can only be called a devoted following, to the point that the line of customers often stretches around the building, even in bad weather. Carl's is seasonal, and closed each year from the Sunday before Thanksgiving until the Friday of Presidents Day Weekend.
