61 Aldwych

61 Aldwych is a building on Kingsway in London. The building was constructed in 1914 as three conjoined blocks called India House, Empire House, and Connaught House. In 1915 a fourth block, Canada House, was added at 14 Kingsway.

In 1919, the Air Ministry took up quarters at 61 Aldwych, at which time the building became known as Adastral House. From 1955, the building was the headquarters of Associated-Rediffusion/Rediffusion London, Independent Television News (ITN), TV Times magazine, the Independent Television Companies Association and, at first, Associated Television. Later, it was the initial base for Rediffusion's successor, Thames Television. After Thames moved out, it was the headquarters of the General Register Office for England and Wales and subsequently of ExxonMobil. In 2025, the building was acquired by the London School of Economics and Political Science (LSE). It is now known as 61 Aldwych.
