Weeksville Preservation Site: Brooklyn, N.Y.

James Weeks, a freedman, purchased land in 1838 in what is now Bed-Stuy. He established Weeksville, a village of free African Americans — laborers, laundresses, craftsmen, doctors, entrepreneurs and professionals. The community was "rediscovered" by community activists in 1968, and in 2005 the Weeksville Heritage Center restored four houses, which feature furnishings, clothing, artifacts and photographs dating back to the 1800s, and opened them to the public.

16th Street Baptist Church: Birmingham, Ala.

Harriet Tubman Museum and Learning Center: Cambridge, Md.

Exhibitions in this small museum offer details on the life of Tubman and some vivid history of Underground Railroad activity in the mid-1800s. Tubman was born nearby and spent much of her early life in this area. The proximity to safer areas in Pennsylvania attracted hundreds of slaves to escape from plantations concentrated in this area.

National Underground Railroad Freedom Center: Cincinnati

This museum provides a comprehensive tour of the plight of slaves from their capture in Africa to their shipment to America and enslavement.

Congo Square: New Orleans

In her important book Congo Square: African Roots in New Orleans, historian Freddi Williams Evans has documented the history of Congo Square, a site in New Orleans where records from the early 1700s document that freed and enslaved Africans gathered to share and perpetuate traditional African cultural practices. Today that square still exists, just outside the French Quarter in Louis Armstrong Park, and black musicians and other culture workers continue to gather there.
