Horseley Fields Junction (grid reference SO923986) is a canal junction at the western limit of the Wyrley and Essington Canal where it meets the BCN Main Line, at Horseley Fields east of Wolverhampton, in the West Midlands, England.
The first canal into Birmingham was authorised by an Act of Parliament in 1768. It was designed by James Brindley and was a contour canal, weaving its way across the landscape in an attempt to stay on one level. It was to run from Gas Street Basin to Aldersley Junction, where it would join another of Brindley's Canals, the Staffordshire and Worcestershire Canal, which was under construction at the same time, and would link the Trent and Mersey Canal to the River Severn at Stourport on Severn. The line was finished through to Wednesbury, where there were coal mines, by 1769, and the link to Aldersley Junction, which included a flight of twenty locks, later increased by one, and passing through Horseley Fields, was completed in 1772. The Birmingham Canal company became the Birmingham Canal Navigations (BCN), following an amalgamation with the Birmingham and Fazeley Canal in 1794.
The Wyrley and Essington Canal was planned to serve the coal mines at Sneyd and Essington, bringing coal to the population of Wolverhampton and Walsall. It was authorised in 1792, and from Sneyd Junction, where the canal headed northwards to the collieries, the main line ran to the west to meet the Birmingham Canal at Horseley Fields, while a branch ran to the east to Birchills Junction, near Walsall. Construction started, but in 1794, the company obtained a second Act, which effectively made the Birchills Branch into the main line, and extended it to Ogley Junction, after which it descended through 30 locks to reach the Coventry Canal at Huddlesford Junction. The whole canal, including the junction at Horseley Fields, opened on 8 May 1797.
