Important for the dissemination of the style was Robert Billings' (1813–1874) four-volume work "Baronial and Ecclesiastical Antiquities of Scotland" (1848–52). It was applied to many relatively modest dwellings by architects such as William Burn (1789–1870), David Bryce (1803–76), Edward Blore (1787–1879), Edward Calvert (c. 1847–1914) and Robert Stodart Lorimer (1864–1929) and in urban contexts, including the building of Cockburn Street in Edinburgh (from the 1850s) as well as the National Wallace Monument at Stirling (1859–1869). Dall House (1855) and Helen's Tower (1848) have square-corbelled-on-round towers or turrets. The rebuilding of Balmoral Castle as a baronial palace and its adoption as a royal retreat from 1855 to 1858 by Queen Victoria confirmed the popularity of the style.
