The facade of Exeter Cathedral appears to have been constructed in three layers. In the first layer there is the gable of the cathedral with a traceried window which peeps over the battlements of the second layer. This layer, which is battlemented, includes the lower aisles and a large western window which has within its arch a circle pattern of elaborate stone lace. Across the entire lower front of the building stretches a stone screen with three doors into the nave and the aisles. The screen is tiered with niches containing numerous statues.
