One response to this popularity was in commissioning the construction of replica castles. These were particularly popular at beginning of the 19th century, and again later in the Victorian period. Design manuals were published offering details of how to recreate the appearance of an original Gothic castles in a new build, leading to a flurry of work, such as Eastnor in 1815, the fake Norman castle of Penrhyn between 1827 and 1837 and the imitation Edwardian castle of Goodrich Court in 1828. The later Victorians built the Welsh Castell Coch in the 1880s as a fantasy Gothic construction and the last such replica, Castle Drogo, was built as late as 1911.
