all the senior children had been transferred to a new school in Chelmsford Avenue. During the late 1920s a maternity hospital was established in Second Avenue using converted council houses. This was incorporated into a new building which opened in 1933. In 1943 a number of people were killed and houses were damaged when butterfly bombs were dropped on the estate during a German air raid on Grimsby. New Nunsthorpe and Bradley Park The absorption of Scartho into Grimsby made available more land for house building. The pre-1928 boundary between Grimsby and Scartho ran past the Scartho Road Institution (now part of the Diana, Princess of Wales Hospital) to what is the present-day rear gate of the hospital grounds at the end of Second Avenue, next to the resource centre. From there it continued westward through fields that would eventually become part of the New Nunsthorpe council housing development. It ran south of what is now Redbourne Road, crossed Winchester Avenue, ran to the north of Kirkstead Crescent, along Scawby Road until it reached Stainton Drive. The amalgamation made this boundary obsolete. In this post-Second World War New Nunsthorpe development the streets were mostly named after Lincolnshire villages, with the exception of Winchester Avenue and a few streets in an area of private housing, which were named after historic English towns. The development included the single-storey prefabricated buildings (prefabs), which were built in 1946 to help alleviate the housing shortage. In 1947 a large wooden hut was purchased and erected in Burwell Drive. This became the estate's earliest community centre, opened in 1949, at the same time the Nunsthorpe's first community association was formed. In 1951 saw the Nunsthorpe Nursery School opened, and in 1952 the branch library in Wootton Road was established. In 1963 the Viking Superstore, which had been converted from three smaller shops into one self-service supermarket, was opened in Second Avenue. Coronation Street stars Pat Phoenix and Philip Lowrie addressed an estimated crowd of 5,000 people in the open air before the official opening During the late 1970s the Bradley Park Estate was built on land between Stainton Drive and the Bradley Recreation Ground. This land had once been part of Bradley parish. Some place names in Bradley Park, such as Bremerhaven Way, reflect Grimsby's links with its twin town, although Wymark View was named after the actor who was born in nearby Cleethorpes. Dolby Vale
