If walls could talk, these are the stories they would tell! A great bridge is built spanning a deep valley to the south of the Royal Mile. Under its 19 enormous arches, in a catacomb of underground chambers, a community begins to thrive. Trades, first legal and then illicit, flourish - and in these hard times there is nothing that cannot be bought or sold for a purse of gold! Such a parcel of rogues in a nation!

The underground vaults were created in the late 18th century, abandoned by the 1830s - and only opened again to the public in 1996. The labyrinth of corridors and chambers you visit remain unchanged from two hundred years ago. Visit this unique attraction and capture a very special moment in the evolution of this city.
