In 1894, philanthropist Mary Schenley presented the deed to the Block House to the Daughters of the American Revolution (DAR).

[11][12] She did this specifically so that the structure might be preserved for future generations:You are to preserve and keep this relic of a bygone past, and to gather and preserve all obtainable history and tradition in regard to it, and you are to beautify and adorn it and to make it the receptacle of relics bearing on the Colonial and Revolutionary periods of its existence....I will therefore...leave the ladies of your Society, who have the history of western Pennsylvania at their finger ends, to tell the story of the chivalrous Frenchmen, cruel, crafty Indians, courageous British, and intrepid Colonists.

Industrialist Henry Clay Frick purchased all of the land surrounding the Block House in 1902, shortly before Schenley's death.

Following lengthy litigation, the Supreme Court of Pennsylvania ruled in favor of the DAR and the Block House, enabling its continued preservation.

Although the Block House resides within the boundaries of Point State Park, it is owned and operated by the Fort Pitt Society of the Daughters of the American Revolution.
