Anne Blessing grew up in a classic antebellum house with double-decker porches and gorgeous brickwork, just steps from Charleston Harbor. For years, the home in Charleston, S.C., had been a stop on a popular historic home tour.

"Normally, people want to see the fancier parts of the house," Blessing said. "You know, where in Colonial times they would have taken people upstairs to the nicer parlor; the dining room, of course, with the beautiful wood and all the molding."

This weekend, for the first time, visitors will skip the formal areas and go straight to the kitchen. What was once the kitchen house has been connected to the main house. With its wooden beams and massive hearth, it's a favorite hangout spot for the family. But as Blessing has learned, it's also where enslaved people once spent most of their lives, toiling over hot fires.

"If you were the cook, you probably just slept on a pallet in this room — and maybe with your whole family as well," she said.

The tour is called "Beyond the Big House." Its organizers — the Slave Dwelling Project and the Historic Charleston Foundation — hope to raise awareness among visitors and residents of Charleston that many former slave quarters have been hidden, and forgotten, among the city's majestic homes.

"I want them to know that behind all that they can witness from the street is the rest of the story," Joseph McGill, founder of the Slave Dwelling Project, said. "The story of those who were enslaved, those whose labor provided the wealth for those nice, beautiful places that they see."

The tour comes at a time when the question of how to remember the ugliest parts of U.S. history continues to divide the country — as the recent violence over the fate of Confederate monuments in Charlottesville, Va., where a woman was killed after a white nationalist rally, again reminded us. Charleston is a city with its own painful racial history dating to the slave trade.

The places where enslaved people lived and worked were concealed by design, says Lauren Northup, director of museums for the Historic Charleston Foundation. At the Nathaniel Russell House Museum, another stop on the tour, a tall fence once divided the formal gardens in front from the work areas in back, where slaves grew vegetables and raised livestock, Northup said.

"So in the back, we have all of this work going on, and then in the front, we have these very beautiful formal gardens," she said. "The only way that you could really even see from the front into the back was if you looked out just one side of the house and then over that fence, to see the labor that was going on in the back."

Past tours have discussed some former slave quarters, but they've never been the focus of a tour before — even though the city was central to the slave trade.

The goal is to tell the full story of the city, said Kitty Robinson, Historic Charleston Foundation president and CEO.

That story, she says, is "only complete when everyone's story is told."

Historians estimate some 40 percent of enslaved Africans passed through Charleston's port.

Their labor has left literal marks on the city, including Blessing's home. She said she has always loved the bricks that make up some of her walls.

"They change colors in different light and they kind of contract and expand with the weather," Blessing said. "I've always thought of them as a work of art, and of course, I always knew that they were handmade, but I had never thought about the details."

What she didn't realize until she met McGill was that some of the indentations in the bricks are the fingerprints of the slaves who made them.

"That's the evidence of the enslaved ancestors reaching out to us, saying, 'We were here. Tell our stories,' " McGill said.

"And when I go and I put my fingers in those prints, my fingers are way too big — which is an indication that there were children, enslaved children, you know, making those bricks."

McGill says it's important to preserve and remember the lives and work of enslaved people whose names have often been forgotten.

Blessing agrees, even if it means facing unpleasant truths about the history of her city and her own home.

"I think it's important that as a country, we talk about it. It's such a major part of our history; it's so much of how we've built our country," Blessing said. "And I think anything that you don't talk about for a long time is going to come out at some point."
