The entrance is at the top of a wide flight of steps leading up from Hope Street. Above the entrance is a large wedge-shaped structure. This acts as a bell tower, the four bells being mounted in rectangular orifices towards the top of the tower. Below these is a geometric relief sculpture, designed by William Mitchell, which includes three crosses. To the sides of the entrance doors are more reliefs in fibreglass by Mitchell, which represent the symbols of the Evangelists. The steps which lead up to the cathedral were only completed in 2003, when a building which obstructed the stairway path was acquired and demolished by developers.
