CNN  — 

Maj. Gen. Gordon Granger of the Union Army announced to the assembled crowd at Ashton Villa in Galveston, Texas, “In accordance with a proclamation from the Executive of the United States, all slaves are free.”

It was June 19, 1865.

Never mind that President Abraham Lincoln’s Emancipation Proclamation had been written and read more than two years earlier. Juneteenth, named for the June 19 declaration, started as a celebration of emancipation day in Texas and eventually spread to other states. With celebrations dating back to 1866, Juneteenth now commemorates the end of slavery in the United States.

“America cannot understand its own history unless the African-American experience is embraced as a central factor in shaping who we are and what we have become as Americans,” said Lonnie G. Bunch, founding director of the Smithsonian National Museum of African-American History and Culture in Washington.

In honor of Juneteenth, here are eight destinations that will enlighten and educate visitors about the road to emancipation and a complicated period in US history:

Montgomery, Alabama

In 2018, two new places opened in Montgomery that fill in some of the gaps in understanding and honoring this part of US history.

The National Memorial for Peace and Justice is the nation’s first memorial dedicated to the legacy of African Americans terrorized by lynching in the years after the Civil War. The memorial is a somber – but necessary – reminder of the more than 4,000 black men, women and children who died at the hands of white mobs between 1877 and 1950.

About a 15- to 20-minute walk away through historic downtown Montgomery is The Legacy Museum: From Enslavement to Mass Incarceration.

The museum is on the site of a former warehouse where enslaved people were imprisoned, and it shows in brutal detail what it was like for people waiting on the auction block to be sold. From there, the museum traces the struggles of black people up to the mass incarcerations of today.

Cumberland Island National Seashore, Georgia

The National Park Service started “Lands and Legacies” tours of this protected area in 2011, taking visitors on a rugged full-day tour via motorized vehicles to sites that include places related to African-American life on Cumberland Island.

The former plantation on the island belonged to Robert Stafford, who by the 1850s had some 400 enslaved people tending his land and working in his house. Another tour stop is the settlement at the north end of the island built by freed individuals from the Stafford Plantation, whose descendants remained on the island through the 1960s.

Up the coast closer to Savannah is Ossabaw Island, the first Georgia State Heritage Preserve. It has a strong African-American history connection, particularly seen in the three cabins dating between 1820 and 1840 – built from shells, sand, lime and water to house enslaved people. The cabin area is now a historic preservation and archaeological dig site.

Philadelphia, Pennsylvania

Philadelphia, a birthplace of American independence, was also a city of slaveholders.

The 1780 census reported that 6% of Pennsylvania’s population was enslaved and most of them were living and working in Philadelphia. Although laws abolishing slavery were passed in Pennsylvania that year, their enactment was so gradual that some people were not freed for another 40 years.

Cliveden, the 18th-century home of the Chew family, immerses visitors in this part of America’s past in the Philadelphia area of Germantown. Its unusual two-story slave dwelling has been restored and is open to visitors, as is the main house. Cliveden also holds a large archive of Chew family documents that includes household inventories of property (enslaved individuals are among the “items” listed) and even the measurements of enslaved individuals’ feet for a local shoemaker hired to make their shoes.

In the area: The unassuming colonial Johnson House was owned by an abolitionist Quaker family, who made it a “station” on the Underground Railroad in the 1800s. Today it’s a stop on the “Quest for Freedom” self-guided driving tours developed by the Pennsylvania Tourism Department.

They were the first African-American regiment of troops to reach the battlefields of World War I, but they were assigned to the French Army because of racial tensions among US troops. McVery was awarded the Croix de Guerre by the French government for his bravery in combat.

A large gap in the Smithsonian’s extensive coverage of US history was filled when the National Museum of African American History and Culture opened in September 2016. It was built on the last available land on the National Mall.

The story begins with the 15th-century transatlantic slave trade and takes visitors through the Civil War and the Emancipation Proclamation up to the history of recent years.

You can also learn about the all the contributions of African-Americans to the arts and culture of the United States at this museum.

Exhibited items include everything from shackles used on enslaved people to the handcuffs used in the 2009 arrest of Harvard University professor Henry Louis Gates Jr. in front of his own home.

Nicodemus, Kansas

In the years immediately after emancipation, Kansas wanted settlers, and newly freed people in Kentucky wanted a home where they could raise their children in peace and safety. It seemed like the perfect match, but when groups from Kentucky relocated to Graham County, Kansas in the 1870s, they were stunned by what they found there.

“My husband pointed out various smokes coming out of the ground and said, ‘That is Nicodemus.’ The families lived in dugouts. …The scenery was not at all inviting, and I began to cry,” 30-year-old Willina Hickman wrote in 1878.

What those newly freed people made of the place is the focus of the Nicodemus National Historic Site. The town, incorporated in 1877 and named for an escaped slave, never had a huge population, but it is the oldest surviving African-American town west of the Mississippi. Park-ranger tours take in five historic buildings and cover the well-documented history of the town and its people.

St. Helena Island, South Carolina

Gullah/Geechee Sea Island Coalition
Visitors can learn more about history at the Penn Center historic St. Helena Island, South Carolina.

The heart of Gullah culture, this island near Beaufort, South Carolina, is home to the Penn Center, a school, job training facility and a safe haven for freed people as early as 1862 after the Sea Islands were occupied and liberated by Union troops.

The strength, unity and continuity of the community, most of whom trace their heritage directly to West Africa, has long been an inspiration, so much so that the Rev. Martin Luther King Jr. is thought to have drafted his “I Have a Dream” speech while visiting there.

Wander through the town of Frogmore, visit studios and shops selling the work of local artists and craftspeople, and sample the Lowcountry cooking derived from traditional African dishes that has sustained the region for generations.

St. Helena Island is an excellent place to explore the Gullah culture that grew within the communities of enslaved people from western and central Africa – developing and refining its own language and traditions – and that is very much alive today.

Charleston, South Carolina

From the silhouettes of the buildings to the characteristic ornamental ironwork that adorns them, African-Americans, both enslaved and free, literally built the city of Charleston, and their descendants comprise much of Charleston’s population today.

One neighborhood of interest is Harleston Village, where you’ll find 1820s houses built by Richard Holloway and Morris Brown, free Black men who owned the homes as investment properties. Look for the ironwork of master blacksmith Philip Simmons, who learned from master blacksmiths in the early 20th century and carried on Charleston’s ironwork tradition into the 21st century.

Charleston also offers a look at urban Gullah culture.

A long-awaited International African American Museum is set to open to the public in Charleston on June 27. The building is set on Gadsden’s Wharf, the arrival port of nearly half of the enslaved Africans brought to North America.

The museum tells the story “of how Africans and African Americans — through their labor, resistance, and ingenuity — have shaped every aspect of our world,” the museum’s website says.

Allensworth, California

Westward migration of freed people from the South eventually led to towns such as Allensworth, chartered in 1908 in rural Tulare County, California. Town founder Col. Allen Allensworth was born enslaved in Kentucky in 1842 and became a military chaplain after the Civil War. What drove him was a desire to nurture self-reliance and security among communities of freed people.

The town flourished until the Great Depression, and by the 1970s, only a few residents remained. California designated it a state historic park in 1976, preserving and restoring the buildings, including Allensworth’s home, Frank Milner’s barbershop, the First Baptist Church and the very first branch of the Tulare County Free Library.
