My thanks to Paul Andruss for letting me use this photograph from Moreton Corbet castle. It was built in the 1100s then became an Elizabethan Manor House with the great big windows (like Hardwick Hall). Glass was taxed so the super-rich liked to use windows to display their wealth. It was damaged in the Civil war and abandoned in the 18th Century. It is on the outskirts of Shrewsbury.
