History The school is on the site of South Park High School, which had originally opened in May 1922 as an all-girls grammar school (South Park Girls' Grammar School) for the south of the city. New buildings were added in October 1938 and extensions in 1962 and between 1974 and 1977. It became co-educational in September 1974. The school was closed on 27 July 1989 due to falling numbers. South Park had been originally intended for 200 pupils, however, by the time it closed its size had reached 900. The school was reopened as The Lincoln School of Science and Technology in September 1992, admitting only year seven pupils in its first year, growing in size each year as a new year group joined. Its name changed at the end of 1999 to The Priory LSST, after the nearby St. Katherine's Priory. In 2008, the school transferred to academy status under the newly formed Priory Federation of Academies, changing to its current name, The Priory Academy LSST.
