An historic work of maritime ecclesiastical architecture has found terrestrial sanctuary in a heritage religious building. The St Thomas Chapel, originally a component of a nineteenth century ship commissioned for the Anglican Church’s Melanesian Mission, has been encased like a jewel in a well-crafted container inside St Matthew-in-the-City. The box and its twin, which houses a small kitchen, do not compete with the architecture of the host building: a sympathetic Architect has achieved an adroit reconciliation of difference and deference.
