This is the Wielki Mur Chiński icon for Windows 10. Here we go. Optimized for 32x32 px, these are the simplest icons in the line style. Downloadable formats are PNG and SVG, among others. Icons8 icon pack is unique in providing a huge number of icons designed by the same team of four designers who create the new icons every working day in the same style and with the same quality. Same cool as the Bat Face, huh.
The middle of the icon looks like an ancient castle with three pillars on top and a passageway underneath. Behind and in front of the central piece are parallel lines that run away and to the castle portion. Behind the central image the lines zig zag whereas the lines in front are smoother and linear.
