 After years of controversy and discussion with debates about its location, construction of the Cathedral Church of St. Peter and St. Paul, the Washington National Cathedral on Mount Saint Alban was eventually begun in 1897, and mostly completed by the 1980s, testifying to its founders' and visionaries' original conceptions.Memorial slabs recognizing Bishop Claggett and his wife are mounted in the basement outside the chapel dedicated to St. Joseph of Arimathea.On November 27, 1800, the United States Senate at its first session in the new north (Senate) wing, of a barely serviceable Capitol building selected the Right Reverend Claggett as its third chaplain.
