[2][3] Docena is a community in the Warrior coal field in unincorporated western Jefferson County, enclosed within the corporate limits of Adamsville.

The area of the present village of Docena was first developed in 1905 by the Colored Methodist Episcopal Church as a campus for their planned college.

Prisoners were brought to the site on the Kansas City, Memphis and Birmingham Railroad, and the same line was used to haul their mined coal to coke ovens for use at the company's Ensley Works.

In 1912, under the direction of company president George Gordon Crawford, the practice of convict leasing was abandoned at TCI's mines.

The company hoped to attract better quality, more settled and dedicated workers by creating a company-owned village with modern sanitation, orderly houses, schools, churches, and recreation opportunities.

Each house had a yard and a privy building at the alley which contained a coal scuttle and garbage bin, all serviced by TCI sanitation department trucks.

Other recreational and artistic opportunities included industrial league baseball, weekly dances, community sings, company sponsored lectures and literature libraries covering technical topics on mining and manufacturing, and various competitions for gardening and decorating the houses.

At that time starting wages for a miner were $2 per day and renting a cottage cost $6 per month, with utilities included.

The program of social welfare continued at full strength through the 1920s, but the company's commitment to it was tested by numerous factors that emerged during the Great Depression of the 1930s.

TCI workers living in the houses were given the first option on the properties, with the company offering a financing plan to help them make the transition from renters to owners.

The mercado, which stayed open as the Lucky Shopping Center, managed by A. J. Tortorici, closed soon after the post office was relocated to a manufactured building nearby in the late 1990s.

The churches have remained active and a new storage building and Boy Scout meeting hall were built near the baseball field.

The Adamsville Industrial Park, adjoining the town to the south, included a small retail strip as well as nearby opportunities for employment which have sustained the village as a residential neighborhood.
