There's a large building opposite the junction there with a central glass turret (can't think of a better description really). Just wondered what it was, driven by it a few times and never stopped to look.

Anyone know?

Is it Abbeydale Hall ?
Just googled it and I think it is - now apartments I think.

I went to a wedding reception quite a few uears ago now at a Masonic Hall / Lodge which stands across from that junction. I wonder if that could be it ?.

The building on Abbeydale Rd South, or more accurately Woodland View. As another poster stated, is infact today, Dore Masonic Hall, and Banqueting Suite. Originally built by the Sheffield and Rotherham Licensed Victuallers Assoociation, as Alms Houses for poor and distressed retired publicans. On a piece of land four and a half acres in size. Consisting of 12 cottages and a central reading room and office, and outbuildings ie washouse, outside toiilets etc. at a cost of £6000,for land on which stood two stone semi-detached houses demolished on purchase, and £5700 for the buildings. The foundation stone being laid in June 1877, and the completed building opened on July 4th 1879 by local MP James Arthur Roebuck with great pomp and ceremony, and after proceedings in a marquee on the land to the rear, now the carpark. Further details from Sheffield Telegraph covering a full page on the next mornings issue. (Local Studies Library, Surry Street) it is by perhaps a perculiar twist of fate worth note, that standing on the steps of the Central Library and looking across the Road, the freeze on the building, shows Masonic Symbols, being originally built as a Masonic Hall, and now a Public House, Whilst the building at Dore was built by the LVA and is now a Masonic Hall.
