postern door

The guardsmen left their mounts out-side the walls and escorted her through a narrow postern door, then up endless steps to a tower.

The portcullis was down and the gates barred, so she turned aside to a postern door.

With the same steady and self-possessed action which she had displayed throughout, she crossed the transept, and made straight for a small postern door which led, as I knew, into the garden of the bishop's palace.

He slammed-to the postern door, freeing the stairway, and rushed up to the narrow open archway leading on to the battlements, stumbling in the dim light over the prostrate body of the gagged sentry as he leapt through.
