Milton Keynes is one of the UK's newest cities, having been built in the 1960's and 70's, as such Milton Keynes, is a clean crisp and modern city. It was designed from the ground up with quality of life at the forefront of its layout and overall design. There are lush green spaces: 5,000 acres of parkland, woodland, rivers, lakes and streams. Not to mention 22 million trees. Milton Keynes is not your typical 'concrete jungle' modern city. It isn't a soulless conglomeration of poor quality 1970's tower blocks and architecture. No.
