Architect John Nash designed Carlton House, a glorious example of the Regency style, under the patronage of George IV (the Prince Regent, who ruled in place of George III while the "mad king"was considered too unstable to rule). Carlton House was considered a most extravagant building for its time; it was demolished after the prince's accession to the throne in 1820. In its place Nash built Carlton House Terrace—no less imposing, with white-stucco facades and massive Corinthian columns. Carlton Terrace was a smart address, home to several of the 19th century's greatest luminaries—including two prime ministers, William Gladstone (1856) and Lord Palmerston (1857–75). Today Carlton House Terrace houses the Royal Society (No. 6–9), Britain's most prestigious society of scientific minds; still active today, its previous members have included Isaac Newton and Charles Darwin.
