Ultra-clean pixel art icon at 2x32 pixels, highly legible. Central composition features a stylized wooden fort: post-and-panel walls atop a grey cobblestone foundation that runs toward a tall crenellated tower. A small right-hand tower window graces the tower. To the tower's right, a layered green pine tree with simple geometric shapes. Details simplified to maximize readability at small size, echoing the logic of a 16x16 Simplified Icon, but leveraging the slightly larger canvas for crisper shapes. A subtle, single outline encircles the whole scene for clarity. Palette: rich rustic browns for wood, cool greys for foundations and outlines, and forest greens for the pine. Background: solid neutral grey. Don’t leave any space on the left, right, or bottom; use as much of the space as you can.

The image shows a black and white pixel art of a castle with a tree in front of it, set against a white background.
