Mankinholes is a hamlet in the Metropolitan Borough of Calderdale, in West Yorkshire, England. It is situated in the Pennines and the nearest town is Todmorden. The hamlet is part of Calder Ward in Calderdale Parish Council. It has a YHA hostel, managed by the larger hostel at nearby Haworth. Mankinholes is the starting point for the popular trek up Stoodley Pike (pike being a North-country term for a mountain or large hill). The hill is surmounted by a 19th-century obelisk, 120 feet (37 m) high, also known as "Stoodley Pike", commemorating the end of the Crimean War. The name "Mankin" is believed to have Celtic origins, with the OED recording its first meaning as "fierce wild man". The surname Mankin is found in parish records of the township of Langfield and the parish of Halifax. One theory is that the name derives from an area of caverns, inhabited by mankins. A second theory is that the name means "Mancan's Hollow", with Mancan being an Irish surname, suggesting Irish-Viking settlers.Mankinholes was an early centre of Wesleyan Methodism. Groups met in farmhouses as early as the late 18th century and the first chapel was built in 1814. This was enlarged in 1870 and rebuilt in 1911. An adjacent Sunday School was built in 1833. Mankinholes Methodist Church closed on 1 July 1979, when the congregation joined with that of Lumbutts Methodist Church, situated midway between the villages of Mankinholes and Lumbutts. The Mankinholes Sunday School building still stands and is now a private house, surrounded by a large graveyard.

Summit Tunnel in England is one of the world's oldest railway tunnels. It was constructed between 1838 and 1841 by the Manchester and Leeds Railway Company to provide a direct line between Leeds and Manchester. When built, Summit Tunnel was the longest railway tunnel in the world. The tunnel, between Littleborough and Walsden near Todmorden, was bored beneath the Pennines, a natural obstruction to most forms of traffic. The tunnel is just over 1.6 miles (2.6 km) long and carries two standard-gauge tracks in a single horseshoe-shaped tube, approximately 24 feet (7.2 m) wide and 22 feet (6.6 m) high. Summit Tunnel was designed by Thomas Longridge Gooch, assisted by Barnard Dickinson. Progress on its construction was slower than anticipated, largely because excavation was more difficult than anticipated. On 1 March 1841, Summit Tunnel was opened by Sir John Frederick Sigismund Smith; it had cost of £251,000 and 41 workers had died. On 20 December 1984, the Summit Tunnel fire occurred. There were no deaths and five months later, the tunnel reopened after repairs. The tunnel has remained in continuous use with little interruption since it opened.
