The former Board School at Connah's Quay was one of the 'Northop Board Schools' which were built in the area. It is dated 1881 on its inscription and is now part of the Custom House Lane County Primary School. The building first appears on the second edition 25" OS map, FL X. 10, of 1899. By 2015, the school had been demolished and a small housing estate was later built on site, named 'Cwrt y Tolldy' / 'Custom House Court'.
