Commemorating three Protestants burnt during the reign of Queen Mary, the Martyrs' Memorial was intended as a rebuke to those very high church tendencies which had been instrumental in promoting the new authentic approach to Gothic architecture. St Giles' was in plan, with its long chancel, of the type advocated by the Ecclesiological Society: Charles Locke Eastlake said that "in the neighbourhood of London no church of its time was considered in purer style or more orthodox in its arrangement". It did, however, like many churches of the time, incorporate wooden galleries, not used in medieval churches and highly disapproved of by the high church ecclesiological movement.
