The 125 foot tower was originally stuccoed. The plaster was removed in 1897 and old photographs of the church show the undressed wall. It was faced with Portland stone after World War II. The clock on the West face, with the image of St James, is a 1988 replica of a 1682 original. The figure of St James originally stood between two urns. The tower is plain, with round headed belfry windows, until the spire. At the top is a parapet with stirrup shaped piercings and squat urns on the corners. The stone spire was designed by Nicholas Hawksmoor and is similar to those of St Stephen Walbrook, St. Michael Paternoster Royal and, to a lesser extent, the west towers of St. Paul’s Cathedral. It has three levels. The lowest is square, with a contraption of two columns standing in front of two pilasters protruding from each corner on top of which is an entablature and tiny urns. This is linked to the next stage by corner volutes, with a smaller square stage with more urns, and at the top is a tiny concave stage. The whole is capped with a flag finial.
