The idea of establishing a camp ground on the Mississippi Gulf Coast occurred to Mr. William H. Foster, a Lawyer and member of the Felicity St. Methodist Church of New Orleans, during the year 1870. With the assistance of Rev. John Matthews, D.D., pator of Felicity Church, and many other dedicated Methodist ministers and laymen including Bishop Kenner and through opposition and jeers Mr. Foster never let up.

The property was purchased from Mr. J.H. Kellar, a wealthy soap manufacturer of New Orleans, and a devoted member of the Drayades St. Methodist Church, New Orleans. The ground was dedicated to Almighty god as a camp meeting site in March of 1872. Dr. W.V. Tudor, the eleoquent pastor of Carondelet St. Mehodist Church, offered the first prayer on these grounds at the Consecration and Dedication Services.

Over the years, additional property was purchased. In 1877, the Mobile District of the Alabama Annual Conference and the Seashore District of the Mississippi Annual Confernce were invited to become joint owners and operators of the Seashore Campground with the New Orleans District of the Louisiana Annual Conference. In 1922 a new charter was granted, naming the three annual conference joint owners and operators of the property.

The property was used for camp meeting purposes until 1910. Cabins had been built on the property and many were occupied year round, needing a school - so for that fact the property was used under the name of Seashore Campground School until 1931 when the name was officially changed to Seashore Mehodist Assembly.

During 1963 the other two annual conferences gave title to the Mississippi Conference and they are now the sole owner of the property that is known today as Seashore United Methodist Assembly.
