(Response from Anne Marie Lane Jonah)
What are those big spikes with diamond-shaped heads in the Dauphin Bastion Gate called?
A guess was "escutcheon" but that's not it. An escutcheon is a decorative or protective shield. Most commonly it is the background upon which heraldic emblems are displayed or the plate around a keyhole in a door. Those spikes are called, "diamond headed nails" by John Muller in his "A Treatise Containing the Elementary Part of Fortification," published in 1774. In a French text of the same era there is a reference to "clous … aux têtes rondes." Their purpose was to prevent the wood from being broken apart by axes, not the biggest concern of defenders by the 18th century.
