  Filamentary textures can take the form of braided, rope-like superstructures
in nonlinear media such as plasmas and superfluids. The formation of similar
superstructures in solids has been predicted, for example from flux lines in
superconductors. However, their observation has proved challenging. Here, we
use electron microscopy and numerical methods to reveal braided superstructures
of magnetic skyrmions in thin crystals of B20-type FeGe. Their discovery opens
the door to applications of rich topological landscapes of geometric braids in
magnetic solids.
