In 1784, Latrobe set off on a Grand Tour around Europe, visiting Paris where the Panthéon, a church dedicated to St. Genevieve, was nearing completion. The Panthéon in Paris, designed by Jacques Germain Soufflot and Jean-Baptiste Rondelet, represented an early example of Neoclassicism. At that time, Claude Nicolas Ledoux was designing numerous houses in France, in Neoclassical style. Latrobe also visited Rome, where he was impressed by the Roman Pantheon and other ancient structures with Greek influence. Influential architects in Britain, at the time when Latrobe returned in 1784, adhered to a number of different styles. Sir William Chambers was at the forefront, designing in Palladianism style, while Chambers' rival, Robert Adam's designs had Roman influence, in a style known as Adam style. Latrobe was not interested in either the Palladian nor Adam style, but Neoclassicalism also was being introduced to Great Britain at the time by George Dance the Younger. Other British architects, including John Soane and Henry Holland, also designed in the Neoclassical style while Latrobe was in London.
