The Bell Tower of Independence Hall in PhiladelphiaAs originally designed and built, Independence Hall had no tower or steeple. These were added around 1750. The wooden steeple had rotted by 1773 and was removed in 1781. In 1828, the city hired architect William Strickland to restore the original steeple. Strickland deviated from the original design, incorporating a clock and additional ornamentation. A recent restoration of the steeple revealed Strickland's modern engineering principles.It consists of a central building with belltower and steeple, attached to two smaller wings via arcaded hyphens. The highest point to the tip of the steeple spire is 168 ft, 7 1⁄4 inches above the ground.
