Arlington National Cemetery

Arlington National Cemetery is the republic's most solemn ground and, approached properly, its most moving half day: 639 hillside acres across the Potomac where more than 400,000 service members and their families lie beneath identical white headstones, the rows running to every horizon. Three stations anchor every visit. The Tomb of the Unknown Soldier, guarded without pause since 1937, changes its sentinels in a precise, silent ceremony every hour (every half hour April through September) — arrive fifteen minutes early, stand where the plaza sightlines open, and let the ritual's exactness do its work. The Kennedy gravesite holds the Eternal Flame beside Jacqueline and two infant children, with Robert and Ted on the slope below and the capital arranged in the view JFK once called so magnificent he could stay forever. Arlington House crowns the hill — Robert E. Lee's confiscated home, its rose garden deliberately ringed with Union dead, the cemetery's origin story told in one landscape. The ground is steep and the distances honest, which is why the hop-on tram and the guided tours earn their fare; this market's combined Arlington-and-DC-highlights tour handles transport, narration, and the sequencing in one booking. Security is airport-style at the welcome center; the tone asked of visitors is quiet and given willingly. Budget three hours; leave changed.

The Tomb is the heart. A single sentinel of the 3rd Infantry's Old Guard walks 21 steps, pauses 21 seconds, turns, and repeats — in rain, blizzard, and August heat, through every night since 1937 — before the sarcophagus holding unknowns of the World Wars and Korea (Vietnam's unknown was identified and returned home in 1998; the crypt lies empty, inscribed Honoring and Keeping Faith). The changing ceremony's inspection — white-glove rifle checks under a relieving commander's eye — rewards the early arrival and front sightline; wreath-laying ceremonies, bookable by groups, add buglers and fold the watching crowd into the ritual. The Memorial Amphitheater beside it hosts the state ceremonies; its small museum holds the medals nations have laid.

The hills tell the national story in sections. Section 60, where Iraq and Afghanistan's dead lie, is the cemetery's living edge — visitors leave stones, photographs, and whiskey, and grief here is present tense, deserving the softest step. The Kennedy slope gathers the 20th century: the Flame, Jackie's quiet slab, Robert's plain white cross by the low wall, Ted beyond. Chaplains' Hill, the Nurses Memorial, the Space Shuttle crews' markers, Joe Louis and Thurgood Marshall and Audie Murphy (the war's most decorated soldier under a standard stone, by request) seed every path with recognitions. Arlington House completes the frame: Lee's portico stares across Memorial Bridge at Lincoln's temple — the war's two poles connected by one axis — and the garden graves below it were the first, planted by a vengeful quartermaster so the house could never be lived in again.

Practicals: enter via the Welcome Center off Memorial Avenue (Metro: Arlington Cemetery, Blue Line) through screening; the grounds open daily year-round. The official hop-on tram loops the big three with narration and spares the hills; walking everything runs five-plus miles of slope. Guided tours — including the Arlington-plus-DC-highlights combination this page books — add the stories the headstones only imply, and matter most for first visits. Funerals proceed daily (up to thirty); routes close briefly, caissons pass, and visitors stop as they do — witnessing one, at respectful distance, is not intrusion but the cemetery's continuing purpose made visible. Photography is welcome except where posted (Section 60 asks discretion); voices low, paths kept, headstones untouched. Pair with the Marine Corps (Iwo Jima) Memorial at the north gate for the closing silhouette against the skyline.
