This is a religious symbol, also used in a secular context.

Being a cross, one of the religions using this symbol was Christianity in the Middle Ages and referred to as a Gammadion, a group of four Greek letter gamma (Γ), the capitalised third letter of the Greek alphabet. Three in a Christian context is a reminder of the Trinity, and each gamma represents one of the four Evangelists, who radiate from the central Greek Cross1, which represents Christ.

Today it is perhaps best recognised as the 1930’s emblem of Adolf Hitler’s extreme-right Nationalsozialistische deutsche Arbeiter-Partei2, commonly known as Nazi. During the Second World War the Swastika was often derisively called the Bent Cross or Crooked Cross3; a slur intended to show that Hitler, an outlaw, was using a Christian cross in a malevolent, non-Christian manner.4

The symbol arrived from Greece via Egypt to Ethiopia. The Greeks themselves inherited the symbol from Armenia. In Armenia it was the ancient symbol of eternity and eternal light (i.e. God). Thus the Agews placed it on the window meaning they had eternal communication or link to God as the window represents “open”.

It’s the right angles of a square meaning truth, rightousness and jestice and they’re equal to 4 90°’s, and when added up they will equal to a full circle 360°’s
