In Scotland, while a similar Gothic style to that used further south in England was adopted by figures including Frederick Thomas Pilkington (1832-98) in secular architecture it was marked by the re-adoption of the Scots baronial style. Important for the adoption of the style in the early 19th century was Abbotsford House, the residence of the novelist and poet Sir Walter Scott. Re-built for him from 1816, it became a model for the modern revival of the baronial style. Common features borrowed from 16th- and 17th-century houses included battlements gateways, crow-stepped gables, pointed turrets and machicolations. The style was popular across Scotland and 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 (architect) (c. 1847-1914) and Robert Stodart Lorimer (1864-1929) and in urban contexts, including the building of Cockburn Street, Edinburgh in Edinburgh (from the 1850s) as well as the National Wallace Monument at Stirling (1859-69). The rebuilding of Balmoral Castle as a baronial palace and its adoption as a royal retreat from 1855-8 confirmed the popularity of the style.
