The Adelphi was built in the 1920's and sits in Attercliffe which was then a very heavily industrialised but also highly populated are of the city. These days, Attercliffe is home to some fantastic sporting venues (thanks to the World Student Games a few years ago) and also - a bit further down the road - it turns into the seedy part of town with its "Private Shops" and some very dodgy clubs for men who want to swap their wives! (Actually, I often think it would be great to swap hubby for a "wife" - I could do with a shopper, cleaner, cook, gardener, taxi driver, washer, ironer etc!)
I think the Adelphi was a bar of some description latterly, but now its empty, unloved and for sale (for about £200,00). Its a very striking building when you drive past it, and I wish someone would buy it and restore it to its former glory (like they did with the Lyceum which went from Theatre to Bingo Hall and then back to Theatre again). But I suspect they won't as its not in the right place.
You can see some old photos of the Attercliffe and the Adelphi if you scroll down on this site.
