One of the things that help bring a community together is to have shared facilities. Memorial Halls and auditoriums were quite popular around the turn of the century as they provided a place for public gatherings, town meetings, plays, community activities etc. These facilities were usually sited near the central governmental district and enhanced the architecture of the region.
Most of these halls were financed by private fundraising efforts, but sometimes matching public funds were also spent. Most of the halls were built in an Art Deco architectural style which was popular at that point in time.
Of course, the larger the city the larger the auditorium.
Some of these memorial auditoriums have been commemorated on spoons. Below are a few examples.
All spoons are sterling silver unless otherwise specified
