If you take a drive along one of the region's busiest junctions, you'll find a rather peculiar building. Made from sandstone, it looks like a relic from a bygone era - and that's exactly the case. The Grade II listed lodge - located within Junction 1 of the M5 in West Bromwich - was built long before the motorway arrived.

The mansion, which was situated about one mile east of West Bromwich , was demolished in 1928. However, the lodge has survived to this day and now forms part of the motorway's roundabout. The lodge is accompanied by a curving brick wall and set amongst a number of trees, shrubs, bollards and a patch of grass. It is hard to reach, with no direct pedestrian access to the motorway island. The lodge can best be seen from the northeastern corner of the roundabout, most visible to drivers emerging from the southbound entry slip road and direction of West Bromwich town centre. Its located on the corner of the roundabout, lying just metres from the tarmac and passing vehicles. Today, it's hard to envisage how the estate would have looked when it was first built, with the motorway and urban sprawl cutting up the land. The hall was once a family home before becoming an orphanage and mental asylum amongst other things. It was knocked down in 1928 after suffering damage from mining subsidence. The lodge, meanwhile, received Grade-ll listed status in 1970 and remains as an interesting local landmark today.
