In an article released on lds.org, President Monson announced that the temple in Philadelphia will be built in the city at the Broad Street and Spring Garden area. Check it out for yourself!
The church also owns some land in Valley Forge and many of the members in the area assumed if we ever got a temple it would be built there. Although it would be a picturesque spot, it would not be practical for many of the members - especially those who live in the city and depend on public transportation.
I wish you could all be here to feel the excitement. Anytime there is a gathering of members, the temple is the first topic of conversation. We are thrilled beyond words to finally receive this blessing we have been praying for for years!
