Maybe it depends in what time period you were married in.I was a convert at 19 years of age in 1959 ,converted my then girlfreind , we were both baptized in Nov.1960 and were married in a Kingdom Hall in Febuary 1961 in Melbourne. I took to the" truth" like water takes to a sponge.
Their were very few Kingdom Halls in Melbourne at that time. The hall we attended at that time was a Masonic hall rented out to the congregation ,everything had to be packed up and put away at the end of our meetings.
The hall we got married in was a few suburbs away it was called the flemington congregation but was actually in another suburb ,which caused a bit of confusion to some of our guests.
Neither my wife or I had any relatives at that time who were witnesses ,they were all"worldly" people as we once were .Looking back it was an interesting wedding reception our family hovering around a keg of beer on one side and the witnesses on the other side of the room (some of which I`m sure would have loved to be on the other side )
I probably put a few peoples nose out of joint even back then .The brother who brought me into the "truth"went to great pains to emphasize how different witnesses were to christendom,one of which witnesses didn`t have a paid clergy , you didn`t have to pay the minister who married you.I took that very seriously,and when it was suggested by our then p.o. that we should compensate the said minister for his services ,I didn`t comply.I thought it was hypocritical .
Sorry I went off on a tangent ,getting back to your question , yes back then it was a big deal for both me and my wife to be married in a building that represented your faith,a Kingdom Hall.
