Manfredo Tafuri: Choosing History

The Ministries Quarter, the MQ, in Ankara, the capital of Turkey, is a very interesting case for modern planning and architecture, conceptualised and developed in the first quarter of the twentieth century. As with other governmental centres and administrative hubs, it was attributed the mission of representing the political power of the newly born nation, facilitating physical, symbolic, cultural and historic channels of producing meaning. However, the successive intervention and involvement of architects, planners, landscape designers, governmental officials and statesmen in the shaping of this unique physical setting has ended with an urban environment wherein the ordinary citizen can nowadays just about grasp some piecemeal and minor messages from the total intentions, and experience habitually only the remnants of the original architecture and distorted elements. Focusing mainly on the first twenty five years of the design and shaping of the MQ, this article concentrates on the generic planning principles implemented in the design of the setting and on how these were undermined by new constraints introduced by globally well-known architects and urban designer, due to the lack of an authoritative principal document defining the original layout, that recorded and helped to preserve its unique spatial qualities at the outset.     

Legislation and the motor car

Vehicle legislation for safety and emission control is led by the USA where half the world's cars and one‐third of the world's road deaths are found. The 1975/6 standards will cause confrontations between industry and government in the U.S.A. and have costly implications for the American people. The rest of the world is affected by what happens in the U.S.A. but for language and other reasons fragmented laws are normal with conflicting requirements for manufacturers who supply the many markets. The greatest force for harmonization of legislation may be the enlarged Common Market including, as it does, the four major European Car manufacturing countries. The Common Market Commission may displace WP 29 of the United Nations as the leading law‐making body. Type approval is the compliance system used in Europe, but the growth in scope of safety and other legislation is bringing into focus a weakness of the system which is reducing production efficiency to an alarming degree. American style self‐certification is not acceptable to European governments.
