Dover was once famed for canneries. This red-brick one produced nationally known brands of canned chicken and plum puddings and was described in the WPA Delaware Guide in 1938 as having “white tile walls, painted cement floors, and men and women workers clad in spotless white.” After 1959, it manufactured Underwood Red Devil ham spreads. The complex was recorded by HAER prior to its sensitive conversion into a state office building.
