The Halycon is a British drama series written for television about a prestigious five-star hotel in London, Great Britain, in 1940 as World War II is in full course. The idea behind the series is to show the impact of the war on life in London from a more civilian point of view. It focuses on members of different social groups in London society and on how the wat influences their work, their relationships and their everyday lives. The Halycon was recorded at the West London Film Studios, though 32 Lincoln's Inn Fields, the former Land Registry Building, served as the exterior of the set. Several critics have referred to The Halycon as a modern-day and more energetic Downton Abbey, the hugely successful British historical period drama TV series.
