Once, every high street had a department store, and they marched the length of Oxford Street.Going up to town to shop at one of these grand emporia and lunch in the top-floor restaurant, or take the children to see Father Christmas, was both a huge treat and completely normal.But the demise of Debenhams, including historic Arding & Hobbs, and Army & Navy at Victoria along with many other House of Fraser stores, confirms that the traditional department store is now an endangered species.In the last five years alone, 83% have gone. Now, for the first time, Tessa Boase chronicles this fabulous world, from Derry & Toms with its roof garden to the Moderne lines of Holdrons in Peckham Rye (now Mr Khan's Discount), as well as Gamages' peerless toy department, Woollands' 21 Shop for cutting-edge Sixties fashion and Chiesmans' menagerie of snakes and lionesses.There is even a guided walking tour of the West End's lost stores.
