The seal of the Society is a reproduction of the old block house (the original church at Tinicum) surrounded by two concentric circles bearing the legend: "The Swedish Colonial Society 1909."

The Society, in 1943, received permission to use the Three Crowns in conjunction with the original seal of the Society, in the manner illustrated, thereby creating the present seal of the Society.

The Three Crowns - Symbol of Swedish Unity and Sovereignty

The Three Crowns device has been used as the emblem of Sweden at least since 1336, when it had long been a familiar symbol of the "Three Wise Kings".

According to one theory, King Magnus Eriksson (1319-64) adopted the device to symbolize his title, "King of Sweden, Norway and Scania".

On the 300th anniversary in 1943 of the landing of Governor Johan Printz at Tinicum, the Swedish Colonial Society, by letter from Minister Filip Wollmar Boström, was authorized to use the ancient Three Crowns symbol in connection with all of the Society's activities. Such privilege was considered to be natural and appropriate to a Society of which H.M., the King of Sweden, is High Patron.
