Malfoy Manor front gates

The gates to Malfoy Manor — the magic wrought-iron gates. These gates permit select individuals (Death Eaters who make some sort of salute a hand with a Dark Mark) to pass through them as if they are smoke, and with others the iron contorts into a face which demands the purpose of the person trying to enter the manor.

July, 1996
Death Eaters Yaxley and Severus Snape entered the Manor through gate."The high hedge curved into them, running off into the distance beyond the pair of imposing wrought-iron gates barring the men’s way. Neither of them broke step: In silence both raised their left arms in a kind of salute and passed straight through, as though the dark metal was smoke."

March, 1997
When Harry Potter, Ron Weasley, and Hermione Granger were caught by a group of Snatchers led by Fenrir Greyback, they were brought to Malfoy Manor gate."One of the Snatchers strode to the gates and shook them.

“How do we get in? They’re locked, Greyback, I can’t—blimey!”

He whipped his hands away in fright. The iron was contorting, twisting itself out of the abstract furls and coils into a frightening face, which spoke in a clanging, echoing voice. “State your purpose!”

“We’ve got Potter!” Greyback roared triumphantly. “We’ve captured Harry Potter!”

The gates swung open."
