Tacoma’s 90-year-old , for years a performance venue for Puget Sound’s Adelphian Concert Choir and the joyous scene of many, many alumni weddings, will be demolished in October. The building needed a new roof, furnace, and earthquake retrofitting, and its location on the perfect site for desperately needed emergency department expansions for two adjacent hospitals made its sale practical, if lamentable. The congregation will build a new sanctuary at South Seventh Street and Tacoma Avenue. About 100 UPS freshmen in the Urban Plunge orientation program helped pack things up for the move. The jaw-dropping stained glass dome, beneath which an upward gazing parishoner could be forgiven for briefly allowing thoughts to drift during Sunday services, will be preserved, its new use yet to be determined.
