Quadrangle

The main quadrangle buildings were opened on 21 October 1926. They were the most extensive addition to the school up until that point, and to this day they comprise a significant proportion of the school buildings.

In attendance at the opening ceremony were:

• Sir Archibald Weigall, high sheriff of Lincolnshire
• Admiral Earl Jellicoe of Scapa
• Tom Kitwood, deputy chairman of the governors.

The large quadrangle formed by these extensions would later be bisected by the Link Block in 1988.
