I took a photograph of where the Old Dutch Church’s door used to be located before Broadway/Route 9 was relocated to another one side of the church, prompting the congregation to move the door to face the new Broadway, thereby eliminating the old door location and reorienting the inside of the church. Well, I found the photograph.
You can see that the stone below the window doesn’t quite match the surrounding stone. This window is the only one to have stonework like this below it; below the other windows a the stone configurations match the surrounding stonework. It was here that the original door was located, which was removed and the doorway made into a window.
This window is now located to one side of the reconfigured inside of the church, facing the altar.
