i was a baptised teenager in the 60's..in birmingham UK. there were 3 circuits that covered the area; so about 30 congregations i imagine. very few had their own hall. most rented school halls, community buildings or anything they could find. it was the dream of most dubs to have their own halls..something to aspire to. it all started to happen in the 70's.
ive no idea how many have recently been stolen.
