Opened in September 1992. The school has the capacity for 420 Primary pupils and a 52 place Nursery. The site was previously occupied by Plashet Lane Board School - sometimes referred to as Arragon Road School, which was built in 1890.  It was later renamed Plashet School and closed in 1940 after war damage.  After being repaired it became East Ham Technical College of Building.  This was demolished at some time between October 1984 (when the image was taken), and January 1993 (when Cleves Primary School opened). Priory Park is on what was East Ham Council's Arragon Road Works Depot and the adjoining Upton Park Goods & Coal Yard. The Council depot finally closed in the late 1970s when it was relocated to the Folkestone Road depot.
