Just the one. And yeah, our church was one of those big city churches that held 800+ people in its heyday in the 50's, but now has dwindled with urban flight. We're hanging on, but it's not easy in this day and age, and with a big building to support. But we have a long tradition, and the architect of the main sanctuary was the same fellow (John Russell Pope) who did the Jefferson Memorial in Washington, DC, and other local landmarks.
