It is one of the premier horticultural display gardens in the United States and is open to visitors year-round to enjoy exotic plants and horticulture (both indoor and outdoor), events and performances, seasonal and themed attractions, as well as educational lectures, courses, and workshops. The Longwood Organ is among the world's great concert organs, with 146 ranks and 10,010 pipes. It has the distinction of being the largest residential Aeolian ever constructed and is a stunning specimen of American Art Deco organ design and engineering. Newly restored in 2011, the organ captures an orchestral sound like no other.
