Chislehurst Caves are a series of intersecting man-made tunnels and caverns covering some 22 miles (35.4 km) in Chislehurst in the London Borough of Bromley. From the mid-13th to early 19th centuries the “caves” were created from the mining of flint and lime-burning chalk. Today the caves are a tourist attraction and, although they are called caves, they are entirely man-made and were dug and used as chalk and flint mines. The earliest recorded mention of the mines and lime-burning kilns above dates from a 9th-century Saxon charter and then not again until around 1232AD; they are believed to have been last worked in the 1830s. During World War I the caves were used as an ammunition storage dump associated with the Royal Arsenal at Woolwich. In the 1930s the tunnels were used for mushroom cultivation.
Although this is not an abandoned place, the feeling of entering and roaming in them tunnels reminded me a lot of the feelings I get when I am in underground places which have been abandoned. Thus I present you some of the photos I got while my visit there and I suggest you pay it a visit if it happens and you are in the vicinity.
