Fen Hollin.

The Closed Door.

The Stewards Door.

The gate at the sixth level in Minas Tirith in Gondor to the walled pathway leading down to Rath Dínen and the Hallows at the fifth level. The name may apply to the pathway as well since Fen Hollin lead to Rath Dínen which is the road between the mansions of the dead in the Hallows. Beside the gate was the porters house who kept the key for the gate. The gate was shut for all save the King / Steward and those who tended the houses of the dead and at times of funeral. The pathway may have been roofed since it was dark and a lantern was needed while going down "between the many pillared balusters looming in the swaying lantern-beam"
