Was it a plantation a training camp a forgotten paradise? Mason Island a small patch of land in the Potomac River has known many lives. Today we stand before Theodore Roosevelt Island its current name a tribute to the 26th president. But its history stretches far beyond his legacy. Long before Roosevelt’s name graced its shores Mason Island was known as My Lord’s Island Barbadoes Island Analostan Island and Anacostine Island. Each name reflects a different chapter in the island’s rich and sometimes turbulent past.

The story begins long ago with the Nacotchtank Indians who temporarily resided on the island around 1668. They called it Anacostine. In 1724 George Mason III acquired the island beginning a new chapter. His son John Mason inherited the island. Around 1796 John Mason built a grand mansion a symbol of wealth and power. He cultivated crops and gardens using both free Black laborers and enslaved people. This grand home hosted lavish parties including one for the future King Louis Philippe I. John Mason also ran a ferry connecting the island to Georgetown a vital transportation link.

The Civil War dramatically altered Mason Island’s fate. Union forces occupied the island transforming it into Camp Greene a training ground for the 1st United States Colored Infantry. Thousands of formerly enslaved people trained there finding hope and opportunity in the midst of conflict. The island served as a testament to resilience and the fight for freedom.

After the war the island changed hands multiple times. The Washington Gas Light Company owned it for a while letting nature reclaim the land. In 1931 the Theodore Roosevelt Memorial Association purchased it. They transformed the neglected farmland into the memorial we see today. Landscape architects painstakingly recreated a natural forest a testament to Roosevelt’s conservationist ideals. Only part of the mansion’s foundation remains a silent reminder of the island’s past.

Today we walk these trails a living memorial to Roosevelt’s legacy and a reminder of Mason Island’s long and eventful history. Each tree each path each quiet corner whispers stories of Native Americans plantation owners soldiers and conservationists. Mason Island’s history is a tapestry woven from diverse threads. It’s a place where the past and present intertwine a poignant reminder of America’s complex heritage.
