 Efforts to improve this housing situation, most successfully with the City Improvement Trust in the late 19th century, cleared the slums of the old town areas such as the Trongate, High Street and Glasgow Cross.Subsequent urban renewal initiatives, such as those motivated by the Bruce Report, entailed the comprehensive demolition of slum tenement areas, the development of new towns on the periphery of the city, and the construction of tower blocks.The policy of tenement demolition is now considered to have been short-sighted, wasteful and largely unsuccessful.
