General Ulysses S Grant National Memorial

Popularly known as Grant’s Tomb (‘Who’s buried in Grant’s Tomb?’ ‘Who?’ ‘Grant, stupid!’ goes a classic gotcha joke), this landmark holds the remains of Civil War hero and 18th president Ulysses S Grant and his wife, Julia. Completed in 1897 – 12 years after his death – the granite structure cost $600,000 to build and is the largest mausoleum in the country. Though it plagiarizes Mausolus’ tomb at Halicarnassus, this version doesn’t qualify as one of the Seven Wonders of the World. The building languished as a graffiti-scarred mess for years until Grant’s relatives shamed the National Park Service into cleaning it up by threatening to move his body elsewhere.
