  In boundary conformal field theories, global symmetries can be broken by
boundary conditions, generating a homogeneous conformal manifold. We
investigate these geometries, showing they have a coset structure, and give
fully worked out examples in the case of free fields of spin zero and one-half.
These results give a simple illustration of the salient features of conformal
manifolds while generalising to interacting and more intricate setups. Our work
was inspired by [2203.17157]
