The foundation manages Monticello — the primary plantation and residence of the founding father and third president of the United States.

Monticello was once a tribute to a man who helped draft the Declaration of Independence — the founding document of the U.S.

Now, the plantation's management has transformed it into a site that emphasizes the fact that Jefferson enslaved people, the New York Post reported.

As the New York Post puts it, Monticello "offers visitors a harangue on the horrors of slavery."

According to Monticello's website, one of the ticketed tours on schedule for the plantation is the "Slavery at Monticello Tour."

This tour highlights the "experiences of the enslaved people who lived and labored on the Monticello plantation," the website stated.

Monticello also offers a free mobile guide app on slavery at the plantation. Monticello's website has an entire section dedicated to slamming the founding father for slavery.

"Thomas Jefferson wrote that 'all men are created equal,' and yet enslaved more than 600 people over the course of his life," the section stated.
