I've been to a couple charity events here recently and had a great time. The hall is huge and has a big stage as well. When you walk in the main entrance, there is lobby area with giant columns and two stairwells leading up to the second floor (where the main hall is). The main hall is a pretty big and is one large rectangle space. If you were hosting an event or wedding, you could probably have 400-500 people in there (just a guess).
It's obviously old but feels a bit dated inside. I know it's supposed to be dated but I feel the space lacks character compared to other spaces in town. If I recall, the walls were covered in paintings of old historians etc.. All of the atmosphere seemed to have been brought in by event planners with the space itself not really contributing to the ambiance on its own.
The last time I was there they had one of the stairwells blocked off as well as that entire side of the building at the top of the stairs. someone rumored that they had major termite problems and were in the middle of construction. Not sure if that's the case but I hope it can all be fixed. If you weren't familiar with the space you wouldn't have even know because the whole area was blocked off with pipe and drape.
I'm not sure what the cost is for the space so I can't speak to it's value compared to other halls/event spaces in the area for rent. I guess it always depends on what type of look you're going for depending on the event itself. read more
