Wolves 1st ever ground
I doubt if I am the first to pin this down as it only took me an hour using Google earth and Old-maps.co.uk websites, but the first ever field used by the Wolves from 1877-1879 was the Old Windmill field at Goldthorn Hill. I have identified this as now being built over by the flats on Bromwynd Close just off Upper Villiers Street. They then moved into 'John Harpers field' which I will soon identify. The Dudley Road ground is well known as Fallowfield Terrace was built almost on the pitch. The school playing fields at the rear of Bromwynd Close gives a good idea of what the Wolves first playing surface looked like. The Windmill Field ground was quite tiny at 1.9 acres: an acre being about 70 x 70 yds, so almost no room around the perimeter for spectators!
Wolves 2nd 'ground'-John Harpers field-opposite the Niphon Works, which happily are still there today, means that this field, used from 1879-1881, was facing Sedgley Street, which had the Kings Arms pub at the bottom end, which was their HQ until the move to Molyneux. The largish field occupied the area between today's Marston Rd and Milford Rd, with Selwyn Close probably running across the half-way line. The Kings Arms is still there, but as the upstars is now a solicitors, sounds like this 1850s pub is about to be closed down.
