The main gates at Parliament Hill are only opened for ceremonial arrivals; pedestrians can access on either side. It does make for a pleasant way to frame Centre Block. Though you have to be taking this shot on a quiet day- I was standing on Wellington Street.
And the ironwork itself is good to use for framing the Peace Tower.
Along the west side of Centre Block, this door in an arched entrance is an entry for Members of Parliament.
I like the pattern of the metal against the wood.
Above the doors, the stonemasons have left one of their peculiar faces in the carvings.
This view is from the west side of the entrance, taking in the arch around it, and also framing the bottom of the Peace Tower beyond it.
