NCC and CCH are the oldest unless Highlands was opened before them. A date on the first 2 has been established but don't know about Highlands. Know it was there in 1959, but not sure how long before that.

 

The Highlands Wikipedia page says the gym was added in 1956.

St Pats is in the new building. I vote Augusta very nice old gym looks older than the 50's but no clue.

Deming had 2 gyms. One was inside the school, it had tile floors and a stage but since then they have converted the old gym into a all purpose area, now the school was built in 1929 and when Deming was open they had sealed the stage area closed, took the ball goals down.

The present Deming memorial gym was built in I believe 1964.

My mom attended a Highlands game to watch my son and she graduated in 1965, she said the gym looked the same as it did almost 50 yrs ago outside of the new floor and goals obviously. So Highlands gym is atleast 50 yrs old.

 

Might be the last time they changed the lights--Still saving energy with those 40 watt-ers??
