While the main entrance to the Bethel Temple evangelical church was "modernized" in the 1950s, the rest of the building's facade (and much of its interior) remains from the building's original use, as a public swimming pool or "natatorium" (it used salt water, piped in from Elliott Bay and heated). The church sold the land it owned across the street, where World Pizza and several small galleries once existed, for condos; now it's preparing to vacate its own building. The developers promise to maintain some of the old natatorium facade; preservation activists want the whole thing saved as an historic site.
