Great place, good for a visit of you're in Newcastle. Worth seeing for a history lesson. Worth seeing for a giggle and a look at some working WWII era guns.
There is a kiddies playground nearby, a reception centre and other event spaces. Not sure about the catering.
Staff friendly.
Sure, it's not The Tower of London, but it is free and it is in Australia.
Good to see, well restored in places, interesting displays. Would like to do the tunnel tour.
