bastion

This term evokes a sense of stubborn resistance and protective strength. In its literal sense, it describes a physical architectural feature designed to eliminate blind spots in a fortress, providing a strategic advantage for defenders to cover the walls.

When used figuratively, it describes a final stronghold of a specific ideology or cultural practice. It often carries a connotation of isolation, suggesting that the belief system is under threat from the outside world and is being preserved by a dedicated minority.
