Burton Constable, Skirlaugh,Yorkshire - A brick manor house was built here c1500. The new house replaced an old pele tower which had served to protect the village since the reign of King Stephen in the twelfth century. Stonework from the pele tower forms the foundation of the north tower (‘Stephen’s Tower’) which, together with the north wing, is the oldest part of the house that survives to the present day.
