St. Edgar's Church is a cathedral built and used by the Hammerites. It is the largest Hammerite church, dedicated to a Hammerite hero, St. Edgar. Located in the Stonemarket, within the City, it is surrounded by tall stone walls, the only entrance being the two wooden front gates accessible from the East. The cathedral is explored in Thief: Deadly Shadows, as Garrett is asked by the Keepers to steal the Builder's Chalice.
The priests conduct the church services, in the main hall which has 8 benches, organized into two columns. Many small prayer rooms exist all over the cathedral, complete with holy statues, benches and a podium.
The cathedral holds the crypt of a long-ago Hammerite hero St. Edgar. A particular day of every year is a special holy day, reserved in his honor, during which the Hammerite priests conduct an all-night service.
