Originally named Legacorry (Log a' Choire; "Hollow of the Cauldron"), the village takes its name from Edward Richardson, who built the manor house, Richhill Castle, around which the village grew up.
At the beginning of the 1600s, the area of Richhill had long been part of the Gaelic Irish territory of Oneilland. In 1610, as part of the Plantation of Ulster, the land was granted to Englishman Francis Sacherevall. His granddaughter Ann married Edward Richardson, who was an English officer, Member of Parliament for County Armagh from 1655 to 1696, and High Sheriff of Armagh in 1665. In about 1660, Richardson built a manor house (now Richhill Castle) on the site that would become Richhill, and in 1664 it was reported that there were twenty houses there. At this time, the village was named Legacorry, after the townland in which is sprang up.
In Thomas Molyneux's Journey to the North (1708) the place appears as "Legacorry, a pretty village belonging to Mr Richardson". It gradually became known as Richardson's Hill and this was shortened to Rich Hill. The original gates to the manor house were wrought by two brothers named Thornberry from Falmouth in Cornwall and were erected in 1745. In 1936 they were moved to the entrance of Hillsborough Castle.
Early in 2012, it was announced that work would begin on a £1.5 million regeneration scheme, which will transform the village and involve the restoration of about 20 buildings. The Richhill Partnership began work in 2013 with the concealing of overhead wires and cables on streets within the conservation area and building restoration work began in early March. The regeneration project along with many other projects will make the village a more appealing place to visit in the future.
