This dignified institution, founded by Charles II in 1682 as a home for veterans, was designed and completed by Sir Christopher Wren in 1692. It consists of a main block containing the hall and the chapel, flanked by east and west wings. There's been little change to Wren's design, except for minor work done by Robert Adam in the 18th century and the addition of stables by Sir John Soane in 1814. The duke of Wellington lay in state here from November 10 to 17, 1852. So many people thronged to see him that two were crushed to death. Today, the hospital is home to bachelor pensioners who fought in World War II or other conflicts.
