This icon is a part of a collection of Arena flat icons produced by Icons8. Icons follow the guidelines of iOS, Windows, and Android and are designed by a single designer, guaranteeing the consistent quality.
It's two columns spaced a little bit apart, creating a doorway in the middle, but connected at the top, creating a bridge-like feature connecting the two columns. There are 3 triangular flags at the top, which are spaced evenly along the top and look as if there is wind blowing on them, all facing to the right. In each of these two column like features, or on each side of the bridge there are 4 colored in squares, which remind me of waffles. They are evenly spaced with two on the top and two on the bottom of each column.
