Ideal for those promised photo ops or else simply sitting and meditating, this former church dating back to around the time of the Great Fire of London was badly damaged by a German blitz bomb in 1941.
Abandoned by the Anglican Church and partly reclaimed by nature, the City turned the ruins into a public park in 1967, and since it then has been providing an ethereal refuge for visitors right in the city centre. Usually frequented by the banker types who work in the area, these days you'll have St. Dunstan mostly to yourself, so make it a stop on a longer walk along the Thames and across London Bridge.
