What prompted the inclusion of the Crypt in the Capitol?

The inclusion of the Crypt in the Capitol was prompted specifically by Congress's desire to honor George Washington after his death. Following his passing in 1799, there was a strong national sentiment to commemorate his contributions and leadership as the first President of the United States. In designing the Capitol, it was important for lawmakers to create a space that would reflect the nation’s reverence for Washington. The Crypt was envisioned as a place where he could be laid to rest, symbolizing his enduring legacy. While the Crypt has evolved to serve multiple purposes over the years, its original intention centered around paying homage to Washington, which is why this answer stands out as the correct choice.
