Revival or mock castles became popular as a manifestation of a Romantic interest in the Middle Ages and chivalry, and as part of the broader Gothic Revival in architecture. Examples of these castles include Chapultepec in Mexico, Neuschwanstein in Germany, and Edwin Lutyens' Castle Drogo (1911–1930) – the last flicker of this movement in the British Isles. While churches and cathedrals in a Gothic style could faithfully imitate medieval examples, new country houses built in a "castle style" differed internally from their medieval predecessors. This was because to be faithful to medieval design would have left the houses cold and dark by contemporary standards.
