Meetings: Fourth Wednesday in January, April, October and First Wednesday in July (Installation)

Number of members @ 30th June 2017 - 37

As with the Harmony and Mechanical Chapters, there was a resurgence of interest in the Royal Arch degree in the 1840s, and this resulted in the formation of the Royal Sussex Chapter in 1848. It was consecrated in 1849. However support was lacking and by 1860 the Mechanical Chapter had merged with it. This was not sufficient to maintain numbers and there were numerous occasions throughout the 19th Century when there were insufficient members present to open the Chapter.

It was not until the 1920s after the first world war that interest was resurrected and by 1925 the Chapter assisted in forming the Duke of Normandy Chapter.
