The framing that supports the dome for our tower was on display this week in preparation for a water test. The framing is believed to be as old as 1748.
As you can see in the upper left photo, the original workers marked each beam and board to know exactly where it would go. This was common practice in the late 18th century. The workmen would have assembled the framing on the ground, marked each piece to be sure it fit, disassembled the framing, hauled it up to the top of the tower, and then completed the final assembly.
