Derby Grammar School

Derby Grammar School buvo viena ilgiausiai gyvavusių mokyklų. Ji veikė nuo 1160 iki 1989.

St Helen's House in King Street, Derby, was built in 1766-1767 as the town house for John Gisborne, an alderman of Yoxall Lodge, Staffordshire, and used to stand in 80 acres (320,000 m2) of parkland.

The house was purchased by the Strutt family in 1801 and in 1860 Lord Belper Strutt offered to sell the house for £3,300 to the governors of Derby Grammar School. Money at that time was a problem for the school, and so he loaned the property to the school for free, on a temporary basis. The boys only grammar school duly moved in for the beginning of the 1861-1862 academic year
