This public demand for modern buildings, combined with Victorian architectural styles falling out of fashion, resulted in dozens of fine Victorian buildings like the intricate glass-roofed Birmingham New Street station, and the old Central Library being destroyed in the 1950s and 1960s by the city planners. These planning decisions were to have a profound effect on the image of Birmingham in subsequent decades, with the mix of concrete ring roads, shopping centres and tower blocks giving Birmingham a " tag. Manzoni's work included the construction of the Inner Ring Road, Middle Ring Road and the Outer Ring Road, which necessitated the purchase and clearance of vast areas of land. As well as this, he designated large areas of land redevelopment areas and set about clearing large areas of slums. Several architects were made the city architect of Birmingham, with the first being Alwyn Sheppard Fidler who held the position from 1952 to 1964, when he walked out following disagreements over his design for the Castle Vale housing estate.
