Bollard is a word that came up at a meeting I attended recently. A small utility building needed protection so it was not struck by cars. The people in charge said it would have bollards around it.
So, what is a bollard?
Originally, it was a short, thick post on the deck of a ship or on a wharf. Ropes from the shop were tied to it. These posts were normally made of iron or steel.
The ones I will be seeing around the building will be landlocked. No ships or wharves involved. And, no ropes on them. Just something very solid so if a car is out of control or skids on ice, it will stop before it makes contact with the building.
