The exhibitions at Aratoi Museum touched a chord with two different sets of families visiting on Thursday.
The main exhibition, entitled "Featherston Military Training Camp ... A Record of a Remarkable Achievement", commemorates 100 years since the camp was created outside of Featherston town, to train troops heading to battle fronts during World War I.
Murray Campbell, Masterton, came with his wife and grandchildren and said he remembered the camp in its World War II incarnation, as a Japanese prisoner-of-war camp.
"I can just remember the watchtowers and the barbed wire."
As a child he came over to Wairarapa on the Fell engine, with the tunnel yet to be built, and he could remember seeing Japanese working on the railway line.
