Jordan Hall is a 1,019-seat concert hall in Boston, Massachusetts, the principal performance space of the New England Conservatory. It is one block from Boston's Symphony Hall, and together they are considered two of America's most acoustically perfect performance spaces. It is the only conservatory building in the United States to be designated a National Historic Landmark. The hall opened in 1903, as a gift of Eben D. Jordan II, a Conservatory trustee and a Jordan of the Jordan Marsh retail store. Its architect was Edmund M. Wheelwright of Boston's Wheelwright & Haven, who later designed nearby Horticultural Hall. The hall's unusual square floor plan reflects its underlying plot of land but despite its shape, the hall has excellent acoustics, and all seats on both the main floor and horseshoe-shaped balcony have unobstructed views of the stage. The hall's prominent organ is modeled upon one found in a church within the former hospital complex of Santa Maria della Scala in Siena, now a museum. The dedication concert of Jordan Hall, performed by the Boston Symphony Orchestra, took place on October 20, 1903, and created quite a stir. Effusive newspaper accounts deemed the hall "unequaled the world over," and the Boston Globe reported that it was "a place of entertainment that European musicians who were present that evening say excels in beauty anything of the kind they ever saw." Jordan Hall has won numerous awards since it restoration in 1995, including the 1996 Massachusetts Historical Commission Preservation Award, the Victorian Society in America's Preservation Commendation, the 1996 Boston Preservation Alliance Award, the Illuminating Engineering Society of North America Award of Merit, and the Illuminating Engineering Society 1996 Lumen Award. The Conservatory's main building, which includes Jordan Hall, was added to the National Register of Historic Places in 1980 and designated a National Historic Landmark in 1994; in both cases the name used is New England Conservatory of Music. Innumerable performances have taken place in Jordan Hall, including some 650 student performances a year as well as appearances by virtually every important classical musician of the past century. That list includes performers Nadia Boulanger, Pablo Casals, the Martha Graham Dance Company, James Galway, pianists Angela Hewitt, Radu Lupu, Rudolf Serkin, Richard Goode, Krystian Zimerman, Garrick Ohlsson, Yundi Li, Richard Stoltzman and Isaac Stern; vocalists Marian Anderson, Dawn Upshaw, Ben Heppner, David Daniels, and Lorraine Hunt Lieberson; guitarists Andrés Segovia, Christopher Parkening, Julian Bream, and Sérgio and Odair Assad; conductors Arthur Fiedler and Kurt Masur; composers Béla Bartók and Aaron Copland; jazz legends Stan Getz and Benny Goodman; and the Budapest, Juilliard, Guarneri and Tokyo string quartets. Jordan Hall is home to From the Top , a National Public Radio classical music show hosted by New England Conservatory alumnus Christopher O'Riley. In addition, the Boston Modern Orchestra Project, New England String Ensemble, and the Boston Philharmonic play many of their concerts at Jordan Hall.
