The plaque on the right says 'Boys Brigade'.
The building was also known as St Anns Parish Hall and stood near the top of Alfred St North, opposite The Mechanics Arms at the bottom of Vicarage St. The pub is now (2013) known as The Pride of Erin, but still has an original Mechanics nameplate on its walls. The Parish Hall is still there too (right hand doorway bricked up) and is currently used by Playworks. (Additional information very kindly supplied by Terry Sleaford).
