In "The End of Something", what does the mill look like on the day that Nick and Marjorie row by it?

Marjorie describes the mill as an "old ruin", but notes that to her, "it seems more like a castle."

"There's our old ruin, Nick," Marjorie said.

Nick, rowing, looked at the white stone in the green trees.

"There it is," he said.

"Can you remember when it was a mill?" Marjorie asked.

"I can just remember," Nick said.

"It seems more like a castle," Marjorie said.

Description:

Ten years later there was nothing of the mill left except the broken white limestone of its foundations showing through the swampy second growth as Nick and Marjorie rowed along the shore.
