White House Cornerstone Laid
The cornerstone of the White House was laid in Washington, D.C., making it the oldest public building in the capital. Designed by Irish-born architect James Hoban, the building was constructed over eight years, partly with the labor of enslaved people.
Why It Matters
The White House became the enduring symbol of the American presidency and democratic governance, serving as the executive mansion for every president since John Adams in 1800.
