A cube
A cube in a square in Porto (Portugal). The vertical axis is the rotation axis of order 3 (the one which goes through two opposite vertices) and this fact makes it appear unusual because we usually visualize the cube in the position in which the vertical axis is that of order 4 (the one that passes through two centres of opposite faces).
