The Parliament that visitors photograph is not the Parliament of Confederation. It is a nineteen-sixteen-to-nineteen-twenty-seven reconstruction designed by John A. Pearson and Jean-Omer Marchand for a country that had just discovered, on the battlefields of the First World War, that it was a country. Eight stops, about one kilometre, end at the Major's Hill Park overlook.

Wellington at Metcalfe: The Gate

The wide view of the central parliamentary lawn. West Block, Centre Block with Peace Tower, East Block. Two architectural eras layered in one frame.

Vernon March's National War Memorial, unveiled 21 May 1939 by King George VI. The Tomb of the Unknown Soldier added in 2000. Three war eras layered on one base.

Lit by Prime Minister Lester B. Pearson on 1 January 1967, with Diefenbaker and LaMarsh present. Thirteen provincial and territorial shields, including the 2017 Nunavut addition.

The 1916-to-1927 Pearson and Marchand Centre Block at its full reach. A Beaux-Arts plan inside a Gothic Revival skin. Closed since 2018 for the largest heritage restoration in Canadian history.

Borden's 1 July 1917 site dedication, the 1919 cornerstone by Edward, Prince of Wales, the 1 July 1927 inauguration on the 60th anniversary of Confederation. The Memorial Chamber holds the Books of Remembrance.

Thomas Fuller and Chilion Jones, 1859 to 1876. Alpheus Todd's iron doors. Michael MacCormac, library clerk, who closed them seconds before the fire on 3 February 1916.

Stent and Laver, 1859 to 1866. Victorian High Gothic, walls 0.9 metres thick at ground level. Expanded 1910 to 1913. Untouched by the 1916 fire because geographically separated.

Ottawa's first park, used as such since Colonel John By's 1826 military reserve. The overlook above the Rideau Canal. The Hill seen from the east, with the Library at the river edge.
Weekday mid-morning, Tuesday through Thursday, between nine and noon. Wellington Street and the Centennial Flame fill with bus-tour and school-group visitors from late morning through afternoon between June and early September; the gate stop reads more cleanly outside of peak. The corridor is quietest on shoulder-season weekday mornings (mid-May, early June, late September, October), and on cold-but-clear winter mornings when the Hill is largely empty. The Centre Block is closed for restoration through approximately twenty thirty to twenty thirty-one; the tour works from the exterior throughout. The Peace Tower carillon plays a short recital weekdays at noon; if you can time Stop 5 around then, the auditory backdrop is the building speaking.
