From WoWWiki

The Cathedral Square in city of Stormwind is so named for the mighty Cathedral of Light, which stands as the greatest monument to the Holy Light in Azeroth and dominates this district. The cathedral, headed by Archbishop Benedictus, is the center of the religion of Light and is thus home to paladin and priest trainers, as well as a first aid trainer.

It is without doubt one of the most upclass sections of the city, and include the residence of most of the city's finest merchants and nobility. It includes selected shops as well as the headquarters to powerful organizations such as the Argent Dawn. It is also an important civic center, housing City Hall and the orphanage.

To get to Cathedral Square, you can head northeast from the Park, northwest from the Trade District, or southeast from the Dwarven District.
