Why is the area called the Crypt?

The area known as the Crypt is referred to by this name primarily because it was intended to serve as the final resting place for George and Martha Washington. As part of the original design for the Capitol building, the space was designated for the interment of the nation’s first president and his wife, reflecting their importance in American history. Although this plan did not come to fruition—Washington was ultimately buried at his estate, Mount Vernon—the name "Crypt" has persisted. This connection provides historical context and emphasizes the intention behind the area’s design.

While the other choices touch upon relevant aspects of the Capitol's history and architectural design, they do not encapsulate the specific reason for the naming of the area as effectively as the intended burial designation for the Washingtons.
