(1913)
Tent with wooden sides ("podsada") is the invention of czech scouts from 1913. At that time the scouts troops used for camping two canvases of Austro-Hungarian army jointed to make pyramid. Once when the scouts was building the camp in the wet terrain, somebody came with the idea - in order the children wasn't laying on the groud - the whole pyramid was raised with the help of wooden 'frame' so it was possible to lay in beds and to stand in the tent.
