This was a pretty typical gym at the time: plenty of wide open space and a variety of available gymnastic training equipment such as traveling rings, medicine balls, tumbling mats, pommel horses and climbing ropes etc. Like most gyms of the period, the training options were basic, but more than enough to obtain good results. The large and very impressive semi-circular beamed roof was specifically designed to allow in plenty of natural light.
The armory was quite a facility, It was built in 1897 and resembled a Medieval castle, turrets and all, as you can see in the exterior shot below.
There was a running track, handball courts and rooms for fencing, wrestling, boxing and any other imaginable physical activity. At the head of this fantastic facility was Dudley Allen Sargent, who virtually founded the discipline of physical education.
