of Wales. In 2018, Cardiff University bought the Temple of Peace from Public Health Wales, though the Welsh Centre for International Affairs remain as leaseholders of part of the building. Building The building is in the form of the letter T, with two wings, and is built of Portland stone. The roofs of the wings are dark red Italian pattern tiles. The wings contain offices and committee rooms, on three levels. Marble Hall The central portion of the building, being deliberately higher than the wings, houses the spacious Temple Hall. Situated on the ground floor and facing the main entrance, it is lined with dove-grey marble to symbolise the emblem of Peace. It serves as a meeting place of numerous cultural and social organisations, with lectures and conferences on international issues held here (featuring speakers from all over the world); it is also a venue for campaigning groups and social events. The Crypt and the Welsh National Book of Remembrance Situated immediately below the Temple Hall, the Crypt houses the first Book of Remembrance. 1,100 pages long, it bears the names of 35,000 men and women of Welsh birth and parentage, and of the men who served in Welsh regiments who died in the First World War. As most died on Belgian or French soil, the bronze used on the glass casing of the Book of Remembrance is French, and the marble pedestal on which it rests is from Belgium. Concealed lighting illuminates the book from the roof of the Crypt. Council Chamber This is used as a meeting place, and is also a library, housing many books with international themes. Wood panelled, it is to be found on the first floor of the building. It contains part of Lord Davies' own book collection. Use as a filming location Much of the 2005 Doctor Who episode "The End of the World" was filmed in the Temple Hall and other parts of the building. The location was used to represent a space station five billion years in the future. Temple Hall was also used in the 2007 episode "Gridlock" and the 2008 episode "The Fires of Pompeii". It was used again in the episodes "Let's Kill Hitler", "Cold Blood" and "Nightmare in Silver." The Temple of Peace has also been used as a filming location for other television shows, including Sherlock with the 2010 episode "The Blind Banker" and His Dark
