From WSB contributing journalist Kathy Mulady: Holy Rosary capped its Centennial Celebration today, with celebrations that included removing the 1937 time capsule (above) from the cornerstone of the church:

The contents were on display a few minutes later across the street in Lanigan Hall, where church members and friends celebrated.

The time capsule included a 1937 newspaper, letters that had yellowed and crumpled with age, coins and other a little envelope of powder that left many wondering what it was … or what it once was:

Holy Rosary’s Father John Madigan thanked everyone for many volunteer hours that were put into the year-long celebration.

Seattle Archbishop Alexander Brunett celebrated Mass and attended the afternoon events afterward.
