This is the Peace Arch, at the Border between Canada and the USA, at Blaine, WA state, about half an hour south from where we live.

On the Canadian Side, it states "Brethren Dwelling Together in Unity" and on the US side, it states "Children of a Common Mother". And inside the arch, on each side, there is a gate fastened to the inside walls, and there it states "May These Gates Never Be Closed".

This Peace Arch is set in a beautiful park, we spent sometime there this evening, we walked through the Arch into the USA (but didn't pass thru Customs), we just remained in the park area, looking at the various flowers, shrubs and trees on each side.
