On 22 March 1911, William Collins, the Bishop of Gibraltar, died on board the SS Saghalien en route from Constantinople to Smyrna and was subsequently buried in the church.

The floor of the church is supported by pieces of railway line placed vertically in the crypt.

The front (east) window was made in 1904 by Charles Kempe and includes a small panel showing Ignatius of Antioch on his way to martyrdom, being greeted in Smyrna by St. Polycarp, bishop of Smyrna, who kisses the martyr's chains.

Inside of the church, the grave of William Edward Collins, Bishop of Gibraltar is on the left of the entrance, to the west.

There is a baptismal font next to the grave, in the shape of a seashell, an ancient symbol of Christian pilgrimage.
