Most of the properties on the terraces are occupied as houses but on Royal Terrace there is a number of hotels, by far the largest being the Crowne Plaza Hotel while on Regent Terrace is located the United States Consulate. Royal Terrace with its views over Leith and the Firth of Forth was popular with early owners who were shipowners and traders in Leith. Some of these were involved in the whisky trade, Leith being a centre for whisky blending and storage, and for a time in the 19th century the street was known as "Whisky Row". Louis-Antoine, Duke of Angoulême (the elder son of Charles X of France, last of the Bourbon kings) and his wife Marie-Thérèse-Charlotte, (the daughter of Louis XVI of France and Marie Antoinette), moved into what is now 22 (then 21) Regent Terrace in 1830. Marie-Caroline de Bourbon-Sicile, duchess de Berry, sister in law of the Duc d'Angoulême, also lived at what is now 12 (then 11) Regent Terrace at that time. Her young son, Henri, the Comte de Chambord, is said to have wept bitterly when his family left for Austria in 1832 as he had become very attached to Scotland. The painter Francis Cadell, one of the Scottish Colourists, lived in 30 Regent Terrace from 1930-1935. The western end of Regent Terrace was closed in 2001 to traffic because of security concerns about the United States Consulate.
