  We show the emergence of topological Bogoliubov bosonic excitations in the
relatively strong coupling limit of an LC (inductance-capacitance)
one-dimensional quantum circuit. This dimerized chain model reveals a ${\cal
Z}_2$ local symmetry as a result of the counter-rotating wave (pairing) terms.
The topology is protected by the sub-lattice symmetry, represented by an
anti-unitary transformation. We present a methos to measure the winding of the
topological Zak phase across the Brillouin zone by a reflection measurement of
(microwave) light. Our method probes bulk quantities and can be implemented
even in small systems. We study the robustness of edge modes towards disorder.
