Mellor Mill was built by Samuel Oldknow in 1790-92 and was burnt out in 1892. It was the largest cotton mill of its time and the template for the architecturally impressive mills that spread through the region. Following Oldknow's diversion of the River Goyt, it was the final flowering of water power, with large stone-built tunnels for water and drive shafts. The site now looks like wild woodland until you walk in and find the deep holes of the wheelpits and cellars. In 2009, excavations at the south end of the mill, in the car park near the millpond, uncovered mill walls, steps down to a cellar with two blocks for mounting machinery and bits of a singeing frame (for removing projecting hairs from a cotton yarn to make it smooth). Subsequently walls at the north end of the mill have been uncovered. In 2011, a grant from the Association for Industrial Archaeology enabled 120 tons of debris to be cleared from the Wellington wheelpit under the centre of the mill and open it for public view. Volunteers have continued to clear the cobbled area in front of the mill, a stable for visitor's horses under the central projection and the 100-metre tunnel for the drive shaft from the Waterloo wheel.
There is more than the mill. Nearer the river, there is the Waterloo wheelpit, the sites of workshops, stables, and gasworks and a tunnel under Lakes Road to Oldknow's mansion and garden. The heritage also includes Bottoms Hall, with Oldknow's model farm and the apprentice house, and the transformation of the south millpond into the Roman Lakes Leisure Park. In September 2012, after two unsuccessful bids, HLF granted £45,000 towards the development stage of the porject "Revealing Oldknow's Legacy: Mellor Mill and the Peak Forest Canal in Marple". The main bid, to be submitted in May 2013, will be for £1.2M jointly with the Canal and River Trust, reflecting Oldknow's promotion of the canal. If approved, the whole industrial complex will be uncovered and opened to the public, plus an innovative approach to digital learning as well as more traditional ways of displaying information.
Mill Mill ilijengwa na Samuel Oldknow mnamo 1792, na ilichomwa moto mnamo 1892. Ilikuwa kiwanda kikubwa zaidi cha kutengeneza pamba wakati huo na kilikuwa kielelezo cha viwanda vingine vyenye usanifu-ujenzi wenye kuvutia vilivyoenea katika eneo hilo. Kufuatia kugeuzwa kwa Oldknow kwa Mto Goyt, ilikuwa maua ya mwisho ya nguvu ya maji, na mifereji mikubwa ya mawe iliyojengwa kwa maji na shafts za kuendesha. Sasa eneo hilo linaonekana kama msitu mpaka unapoingia na kupata mashimo ya ndani ya magurudumu na vyumba vya chini ya ardhi. Katika 2009, kuchimbua katika mwisho wa kusini wa kinu, katika maegesho ya magari karibu na kinu, kufunua kuta kinu, hatua chini ya chumba cha chini ya ardhi na vitalu viwili kwa ajili ya kufunga mashine na vipande vya frame singeing (kwa ajili ya kuondoa nywele protruding kutoka nyuzi pamba kufanya ni laini). Baadaye kuta zilizo upande wa kaskazini wa kiwanda hicho ziligunduliwa. Mwaka 2011, kwa msaada wa Shirika la Utafiti wa Kiwanda, tani 120 za mabaki ya kiwanda hicho ziliondolewa kwenye kiwanda cha Wellington kilichokuwa chini ya kiwanda hicho na kufunguliwa kwa umma. Wajitoleaji wameendelea kusafisha eneo la cobbled mbele ya kinu, stall kwa ajili ya farasi wageni chini ya makadirio ya kati na 100m handaki kwa ajili ya shaft gari kutoka Waterloo gurudumu. Kuna mengi zaidi ya kiwanda hicho. Karibu na mto, kuna Waterloo wheelpit, maeneo ya warsha, stalls, na gasworks na handaki chini ya Lakes Road kwa Oldknow ya jumba la kifalme na bustani. Bottom Hall ni nyumba ya zamani ya Oldknow, ambayo ilijengwa katika mwaka wa 1540 na iliyobadilishwa kuwa Hifadhi ya Burudani ya Maziwa ya Kirumi. "Mwaka 2012, baada ya zabuni mbili zisizofanikiwa, HLF ilitoa £ 45,000 kwa hatua ya maendeleo ya mradi wa ""Kufunua Urithi wa Oldknow: Mellor Mill na Mfereji wa Msitu wa Peak huko Marple.""" Mkataba huo, ambao ulikubaliwa na serikali ya Uingereza, ulikubaliwa na shirika la Canal and River Trust, ambalo linashiriki katika ujenzi wa mfereji huo. Ikiwa itaidhinishwa, jengo lote la viwanda litagunduliwa na kufunguliwa kwa umma, pamoja na mbinu ya ubunifu ya kujifunza dijiti na njia za jadi za kuonyesha habari.
