In that year, the Methodist Church purchased a property named York Castle near Alderton, where they established a Theological College in 1876. In 1896, York Castle closed its doors due to financial difficulties. Despite this closure, the need for education in the area remained a constant challenge to men of vision who embraced the idea which has originally led to the founding of York Castle in 1876. Before the closure, Mr. T. Bramwell had in 1903 set up a Middlesex High School in Brown’s Town. Mr. Bramwell served as principal for over 40 years. After his death, Middlesex High School was renamed Henderson High School in 1947, after a Baptist minister – Rev. George Henderson. Henderson high school closed its doors in 1954.

On a hill side property by the name of Egypt in North-West St. Ann is a high school named “York Castle”, tucked away for the past 52 years and responsible for some of Jamaica’s most prominent scholars. York Castle High School has a rich history and roots dating back as far as 1875.

By this time, the idea of continuing the principle of education found custody in the hands of concerned citizens who renamed the school Northside in 1955.

At the synod of the Methodist Church in 1946, there was a resolution asking the church to recognize its obligation to establish a school for boys, or possibly a coeducational school to be called “York Castle”. A committee was set up which was entrusted with the task of establishing a new school in St. Ann. This committee contemplated a site for this new school. On November 30, 1956, the committee, consisting of educators, churchmen and others met and considered an offer from Northside secondary school that the school be handed over to the Methodist Church. The offer was accepted. with a proposed loan from the Methodist Church and gifts from past students of the former York Castle and the sale of the property which the former York Castle was sited, it was agreed that as of January 1, 1957 the Methodist Church would assume control over Northside Secondary School. the Egypt site was decided on in March 1957 and the stone laying ceremony took place on May 16, 1957. By August, the school was given a full ministerial recognition as a secondary grant aided school now bearing the name York Castle High School.

On January 7, 1958, the new school building was opened with 195 day students and 40 boarders. In February, the official opening of the building was done by the Hon. N.W. Manley, Premier of Jamaica.
