This is a Palace icon. We've made it in iOS style, first introduced in iOS version 7 and supported in all later releases up until now (at least iOS 11). This style is based on thin two-pixel lines and is optimized for 50x50 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 12,800 icons, all in the same style and quality.
The icon is depicting a castle or palace of some kind. The palace is symmetrical with an archway in the middle and five turrets with a prominent tower in the middle. There are two windows on the palace.
