Threshold 3: Atlantic Works Shipyard — Making

Shipbuilding in East Boston

A place is made, not found

1869

Donald McKay stands in a black top hat before the launch of his final clipper ship, Glory of the Seas. It is the culmination of a life’s work—and a threshold between eras.

That same year, the Transcontinental Railroad was completed and the Suez Canal opened, reshaping how people and goods moved around the world. Even as Glory of the Seas entered the water, the clipper era that had made McKay famous was beginning to pass.

For McKay—a Nova Scotian immigrant who became one of history’s great shipbuilders—the launch marked both the culmination of an extraordinary career and the closing of an age.

1928

Another man. Another hat. Another ship. Here at Atlantic Works, the Nantasket rests on Marine Railway No. 2, whose remains are still visible beneath the bridge.

By then, the work had changed. Record-setting clippers had given way to the repair and maintenance of steam-powered vessels like this forty-year-old ferry, which carried passengers between Boston and Nantasket Beach.

Yet the essential work endured: skilled hands building, repairing, and keeping the region moving.

A year later, the Nantasket was destroyed by fire. Before 1929 was over, the crash would mark the beginning of the Great Depression.

Today

You stand on that same East Boston shoreline. The threshold around you was fabricated nearby by Blue Atlantic Fabricators, where skilled hands continue Boston Harbor’s tradition of marine work.

Donald McKay, the worker beside the Nantasket, and the people who made this threshold belong to different generations. Each encountered a place between what was and what could be—and helped shape what came next.

Your own thread now passes through this place, facing the same harbor horizon between what was and what will be.

Each generation helps shape what comes next.

The future is ours to make.
