Andrew Duncan Secret london, rev edn

Aimed at visitors and Londoners alike, this fully updated new edition of Secret London unlocks the city's most fascinating secrets - both above and below ground.

Celebrated historian Andrew Duncan strips away bricks, mortar and tarmac to uncover parts of the capital that even born and bred Londoners may never have seen.

Below ground, he guides readers through an extraordinary honeycomb of structures - from the government's vast system of offices and tunnels under Whitehall and through abandoned Underground stations to Clerkenwell's amazing network of subterranean prison cells.

Above ground, he leads the way through narrow alleyways and cobbled mews, revealing unexpected treasures and describing rarely seen interiors and special collections.

Opening times and addresses, detailed route maps and evocative photographs complement a fascinating text that is sure to delight all urban explorers.
