Collyhurst is an inner city area of Manchester, England, northeast of the city centre on Rochdale Road (A664) and Oldham Road (A62), bounded by Smedley, Harpurhey and Monsall to the north, Miles Platting to the east, Ancoats to the south, and the River Irk to the west. Prominent buildings include two Roman Catholic churches, St Patrick's and St Malachy's. Collyhurst sandstone Much of the red sandstone used for building in Manchester and the surrounding area, including stone for the Roman fort at Castlefield, St Ann's Church in the city centre, Manchester Cathedral and the original buildings of Chetham's Hospital, came from Collyhurst Quarry. Geologists use the term Collyhurst Sandstone for this type of soft red sandstone, which occurs in North West England. It is a fine to medium grained sedimentary rock, created from desert sands blown into dune formations during the Early Permian period when the area which now constitutes the British Isles was within the desert belts to the north of the equator. The rock is not very resistant to weathering and erosion and disintegrates relatively quickly. The quarry was mentioned by John Leland in the description of Manchester in his book. The Itinerary of John Leland in or about the years 1535 to 1543, saying that there was " a goodly quarre hard by the towne". Stone was transported the short distance into Manchester by river on barges or rafts. The quarry is disused and the area around it has been turned into a park called "Sandhills" as part of Manchester City Council's Irk Valley Project. Churches There are now two Roman Catholic churches in Collyhurst, St Patrick's and St Malachy's. There was once also St Edmund's in Monsall Street (architect P.P. Pugin, 1894). The three former Anglican churches have been demolished since they were described by Nikolaus Pevsner in The Buildings of England; Lancashire; I, 1969. The oldest was St Oswald's on Rochdale Road in the Gothic of the 13th century, the architect was E.H. Shellard; the east end was spectacularly picturesque and there was a steeple designed by John Lowe. Lowe was also the architect of the two other churches, the Albert Memorial Church in Queen's Road, 1864, a red brick building with a northwest tower topped by a spire; and St James's in Teignmouth Street, 1874 (this had a steeple at the northwest corner, a porch on the southwest, and a polygonal apse).
