Kensington Palace [SEP] King William III and Queen Mary II
Kensington Palace was originally a two-story Jacobean mansion built by Sir George Coppin in 1605 in the village of Kensington. The mansion was purchased in 1619 by Heneage Finch, 1st Earl of Nottingham and was then known as Nottingham House. Shortly after William and Mary assumed the throne as joint monarchs in 1689, they began searching for a residence better suited for the comfort of the asthmatic William, as Whitehall Palace was too near the River Thames, with its fog and floods, for William's fragile health. In the summer of 1689, William and Mary bought Nottingham House from Secretary of State Daniel Finch, 2nd Earl of Nottingham for £20,000.
