-
Surratt House Museum
The rifles, ammunition, and field glasses John Wilkes Booth grabbed mid-escape after shooting Lincoln were stashed here first, hidden on tavernkeeper Mary Surratt's orders. She was hanged on July 7, 1865, the first woman ever executed by the U.S. federal government.
-
NRA National Firearms Museum
2,500 guns spanning seven centuries fill the NRA's headquarters building, including firearms owned by Theodore Roosevelt, JFK, and Reagan, Napoleon Bonaparte's flintlock fowling piece, Annie Oakley's exhibition guns, and a full-scale WWI trench diorama built to walk visitors straight through it.
-
National Museum of Civil War Medicine
Housed in a 19th-century building that doubled as a furniture maker's shop and undertaker's parlor during the war, the museum displays the only known surviving Civil War surgeon's field tent alongside surgical kits, veterinary-medicine artifacts, and five immersive dioramas walking visitors from army camp through amputation to hospital ward.
-
Dinosaur Land
Over 50 hand-built fiberglass dinosaurs crowd two wooded acres off Route 340, some dating to the park's 1963 opening (as a gift shop called Rebel Korner) with wood-and-wire-mesh frames built by a Field Museum designer, alongside newer additions like a 70-foot purple octopus, a 60-foot shark, and a King Kong you can pose in the oversized hand of.
-
Riversdale House Museum
This Federal mansion was built 1801-1807 as a five-part ensemble for a Belgian merchant's daughter, Rosalie Stier Calvert, on a 739-acre slave plantation - land her son later carved off to found Maryland Agricultural College, now the University of Maryland.
-
Clara Barton Missing Soldiers Office Museum
Clara Barton ran her "Missing Soldiers Office" out of a rented third-floor room here from 1865 to 1868, tracing more than 63,000 missing Union soldiers for grieving families — then the building was sealed up and forgotten for over a century until a routine inspection ahead of planned demolition uncovered her unopened boxes of letters and belongings still sitting in the attic.
-
National Bonsai & Penjing Museum
One tree in the Japanese pavilion, a white pine called the Yamaki Pine, has been in continuous bonsai training since 1625 — it was standing about 1.5 miles from ground zero in Hiroshima on August 6, 1945, and its donor family (the Yamakis) didn't reveal that survival story to the U.S. National Arboretum until 2001. It shares the grounds with a Chinese penjing collection and 105 "viewing stones" kept purely for the shapes erosion carved into them.

Glenstone Museum — Alex Da Corte's Rubber Pencil Devil (Hell House)
Inside Room 6 of the Pavilions sits a neon sculpture shaped like a house on fire — artist Alex Da Corte's 2022 walk-in piece Rubber Pencil Devil (Hell House), commissioned by the museum, which houses his own 2018 video work inside its glowing frame. Da Corte performs in his own videos, in prosthetics and costume, recasting familiar American cartoon imagery as something unsettling.
