Comment Even wimbledon.org uses "Henman Hill" more, 157 pages are indexed by Google vs. around 80 for "Aorangi Terrace" or "Aorangi Picnic Terrace".  Only about 20 pages use variations of "Aorangi Terrace" without saying "Henman Hill".  One All England Club leaflet calls Henman Hill the "Water Gardens", others use "Aorangi Terrace" for the nearby paved refreshment area.
