The Episcopal church you saw must be Trinity Church located about 2 blocks south of WTC-2. It was not damaged on 9/11. However, St. Paul's Chapel, which is affiliated with Trinity Church, is located 2 blocks east of the WTCs. A great deal of wreckage from 9/11 fell on that property.
Yes,it was east. I recall reading that debris fell on the property but little,or no,damage was suffered by the structure itself.
