Popis:	The predictions of nonlocal London theory are confirmed by real-space measurements of the hexagonal-to-square transition in the vortex lattice structure of ${\mathrm{V}}_{3}\mathrm{Si}.$ We observe that the lattice transforms from hexagonal to nearly square over the field range of 0--4 T for fields applied along the [001] direction. Above $\ensuremath{\approx}0.75\mathrm{T},$ we find that the lattice orientation is strongly linked to the symmetry of the underlying ${\mathrm{V}}_{3}\mathrm{Si}$ crystal and has a (100) symmetry plane. Near the rhombus-to-square transition at 4 T, we observe anisotropic long-range translational order, consistent with predictions of the elasticity of the lattice near this transition.
