We've told you about the 1858 Caulkers Riots - when white workers violently ended the Black caulkers' monopoly.

We've told you about the Chesapeake Marine Railway - the Black-owned shipyard founded in response.

Now here's the moment that formalized the exclusion:

September 1865: A strike by white caulkers resulted in an agreement to gradually replace Black caulkers with white workers in Baltimore's shipyards.

This wasn't spontaneous. It was organized. Deliberate. A negotiated plan to phase out Black workers entirely from the trade they'd controlled for 20 years.

Think about the timing: the Civil War had just ended. The Emancipation Proclamation was barely two years old. Juneteenth - the moment enslaved people in Texas learned they were free - had happened just three months earlier.

This is the contradiction of that moment in American history. Legal emancipation was spreading. And economic exclusion was being formalized.

Black ship caulkers didn't disappear. The trade continued in Black families into the early 20th century. But September 1865 marked the official end of their leverage in white-owned yards.

Power gained. Power lost. Power rebuilt differently.

That's the full story.

We mentioned the Chesapeake Marine Railway and Dry Dock Company - the Black-owned shipyard founded after the 1858 riots.

Here's what that actually looked like.

Fell's Point, Baltimore. A full shipyard with a marine railway for hauling ships out of water, a dry dock, and workshop facilities. Over 300 Black workers at its peak - shipwrights, caulkers, carpenters, blacksmiths. All skilled tradesmen building and repairing vessels.

John W. Locks ran it as president. Isaac Myers, the founder, had been a ship caulker pushed out of white-owned yards. Both knew exactly what they were building: a place where Black workers owned the means of production, set their own wages, controlled hiring, and kept the profits.

This wasn't symbolic. It was a functioning, profitable shipyard that competed directly with white-owned operations.

The work was the same - building ships, repairing damaged vessels, caulking seams to make them watertight. But the power structure was completely different.

The legacy of 612-614 S. Wolfe Street didn't end when the monopoly broke. It evolved. From negotiating with white employers to becoming their competition. From trade association to shipyard ownership.

That's what resilience looks like.

As we approach Juneteenth, here's something to understand about being a free Black person in Baltimore in the 1840s-1850s:

You had to prove it.

Certificates of Freedom were legal documents that free Black people were required to obtain and carry. Without one, you could be arrested, jailed, or even sold into slavery.

Richard Jones - the ship caulker who lived at 614 S. Wolfe Street with his family - obtained his Certificate of Freedom in 1832. It listed his physical description (height, complexion, scars), his age, and verified that he was indeed a free person.

He had to pay for it. He had to record it officially. He had to carry proof of his freedom everywhere he went.

Because even in a city with the largest free Black population in the country, freedom was never assumed. It was always questioned.

Maryland laws allowed free Black people to be sold into slavery if convicted of crimes or deemed "unproductive" under an 1832 vagrancy law.

So the ship caulkers who lived at 612-614 S. Wolfe Street were free. But their freedom came with conditions, restrictions, and constant threats.

This Juneteenth, as we celebrate the end of slavery, we're also remembering what "free" actually meant - and didn't mean - for Black Americans before emancipation.

People ask: "How do you restore a 230-year-old building?"

Very carefully.

Stabilization — Keep it from collapsing. In 2005, fiberglass posts held these houses up.

Documentation — Examine, measure, photograph, understand what's salvageable.

Foundation — Rebuild what supports the structure.

Timber frame — Specialists assess every beam. Some saved, some reinforced, some replaced using period-appropriate methods.

Exterior — Siding, roofing, windows, doors, chimney. Materials matched to 18th-century specifications.

Interior — Our focus is now on making these Houses accessible to visitors. Installing missing woodwork and plaster, rebuilding sleeping lofts, restoring spaces where families lived.

Throughout: specialists who understand old buildings. Craftspeople who work with brick nogging, hand-hewn timber, traditional joinery.

Restoration takes time. Money. Expertise. Patience.

But the alternative is watching 230 years of history collapse.

We choose restoration. Down to the last brick or timber.

July 25, 1850. A census taker stops at 614 S. Wolfe Street.

He records nine people living in this two-room, less than 400-square-foot house:

• Richard Jones (50, ship caulker)
• Rebecca Jones (36)
• Six children: Ozius (14), Charles (13), Francis (6), Horace (3), Alex (8), Maria (1)
• Lazarus Arnold (45, boarder)

The boarding house system was common in 19th-century working-class neighborhoods. Families took in boarders to supplement income. Boarders got affordable housing.

For the Jones family, Lazarus Arnold's rent could have meant extra income, a buffer against unemployment, another adult in the household.

For Lazarus, it meant a place to sleep and meals without the cost of his own space. It could have meant a place to get on his feet after having just been freed, or a place to live to be near still -enslaved relatives while he saved money to buy their freedom.

But it also meant no privacy. Shared sleeping spaces. Constant proximity. Minimal personal possessions.

This was survival economics. Not comfortable, but it was how working people made housing work in expensive port cities.

The Ship Caulkers' Houses preserve this reality. Not the myth of how people lived, but the truth.

Nine people. Less than 400 square feet. This is what home looked like.

The story of Samuel Dorrity continues.

Our newest blog post dives deeper into the life of a remarkable ship caulker who navigated and shaped the world around him in the years before and after the Civil War. From Baltimore’s waterfront to San Francisco, Dorrity’s story reveals resilience, ambition, and a life far more extraordinary than most history books ever tell.

If you read the first post, you won’t want to miss the rest of the story.

The Ship Caulkers' Houses almost didn't make it.

Vacant for 50 years. Their future uncertain.

Nobody planned for these Houses to tell this story.

The story of Black ship caulkers who lived here? That was uncovered in 2005 through research. It wasn't marked. Wasn't commemorated. Wasn't protected.

This history survived by accident.

Here's what preservation does: it turns accidents into intention.

It says: now that we know what happened here, we're choosing to keep it. Now that we understand what this place represents, we're investing in its survival.

Preservation is the moment we stop letting history disappear randomly and start making deliberate choices about what we protect.

These Houses could have been gone by 2010. The story lost. The physical connection severed.

Instead, they're standing. Restored. Waiting for interior restoration.

That didn't happen by luck. It happened because people chose to act.

National Preservation Month is about recognizing those choices—and making more of them.

What else is out there, barely standing, waiting for someone to say: "This matters. We're keeping it"?

Last month we told you about the 1858 Caulkers Riots - how white workers violently ended the 20-year monopoly Black ship caulkers held in Baltimore.

So what happened next?

Some Black caulkers stayed, working alongside white workers - but the leverage, the wages, the control were gone. Violence continued through the Civil War. In September 1865, a strike resulted in an agreement to gradually replace Black caulkers with whites entirely.

But here's what the riots didn't kill: the community's ability to organize.

Enter: The Chesapeake Marine Railway and Dry Dock Company. It was founded in 1866 by Isaac Myers and other Black caulkers who'd been pushed out.

If white shipyards wouldn't employ them fairly, they'd build their own.

At its peak, it employed over 300 Black workers. John W. Locks, its president, became one of the wealthiest Black businessmen in Baltimore. Isaac Myers became a national labor and political leader.

The story didn't end in 1858. It transformed.

Economic power. Organization. The refusal to disappear.

When a historic building is demolished, we lose more than brick and timber.

We lose the original construction methods we can no longer replicate. Old-growth timber from forests that don't exist anymore. Physical proportions that reveal how people actually lived. Craftsmanship built by hands long gone.

But we also lose something harder to measure: community memory. The stories that were never written down but existed in the walls. The gathering places where neighborhood identity was formed. The physical bridge between "this is where it happened" and "this is what happened."

Without the Ship Caulkers' Houses, we can still tell you about free Black ship caulkers in Baltimore. We can show you census records and historical accounts.

But we can't let you stand in a 400-square-foot room and ask: "How did nine people live here?"

Once a building is gone, that visceral, physical understanding disappears forever. No amount of documentation can bring it back.

That's why preservation matters. That's why these houses matter.
