The Royal Arch Association of the Fourth Capitular District is an organization that is the union of all Royal Arch Chapters of Freemasonry in southwestern Ohio, centered around Cincinnati, Ohio. Its purpose is to provide support and governance of the constituent Royal Arch Chapters in the Fourth Capitular District and promote Royal Arch Freemasonry in particular and The York Rite in general.
Annually the R.A.A. hosts the presiding Grand Officer of the Grand Chapter of Ohio at a reception in his honor, The York Rite Festival of Southwestern Ohio, and fund raising events in support of future officers of the Grand Chapter.
Meetings are held monthly (except in December and the summer months), starting at 7:30 PM, usually preceded by dinner and are hosted by a constituent chapter.
