The south and west sides of the square were completed in the 1830s, and the rest by 1847. The square takes its name from the landowner,
Sir Charles Morgan, 2nd Baronet, and his family estate
Tredegar House near
Newport, South Wales. One block north of the square is the
Lord Tredegar pub and one block east
The Morgan Arms, on Morgan Street. The industrial town of
Tredegar in South Wales was also named after the Tredegar estate, following the establishment nearby of
The Tredegar Iron Company in 1800, on land owned by the Morgan family.
Coborn School campus named after square Prisca Coborn (1622–1701), the widow of a Bow brewer, left property in Bow, Stratford, and Bocking (Essex) to maintain a school for not more than 50 poor children at Bow; the boys were to learn reading, writing, and accounts, and the girls reading, writing, and needlework. An expansion plan in 1873, to day-school 200 boys and 200 girls (in adjoining buildings) meant the Bocking estate was sold and part of the proceeds used to purchase and extend a building "in Tredegar Square", however clearly shown on the map as narrowly beyond its north-west corner, also known as Stepney Grammar School. The school did not prosper on its own in its new surroundings, and by 1884 was in financial difficulties; the girls' school temporarily closed and a merger took place within a decade. In 1898 Coborn School was moved to 29–31 Bow Road, where it remained until the move to Upminster in 1971, initial plans of which had been well advanced in 1963.
Restoration after damage in the London Blitz The Tredegar Square Conservation Area was established in 1971. The square had become neglected prior to
World War II, made worse when the area surrounding the square was badly damaged by bombing during the war. ==References==
