The millennium clock tower (2nd ed)

The Millennium Clock first chimed on 1 January 2000 and crowds still gather round it in the National Museum of Scotland.

The finished clock tower echoes the form of a medieval cathedral, standing just over ten metres high.

It marks the passing of time but is also a summary of the best and worst of the twentieth century.

The animated construction comprises four sections: The Crypt, The Nave, The Belfry and The Spire.

Each has its own stories to tell and secrets to reveal.

This edition is in a new format and has 12 superb replacement photographs which give close-ups of some of the clock's intricate details.

The clock tower is a collaboration between E Bersudsky, A Sandstrom, T Stead and J Tubbecke.
