The furnaces are preserved in a park or museum, or as a site otherwise open to visitors, or intended to become such.

They are supported by outer frames made of metal, were supplied with pre-heated blast air from external Cowper stoves, were typically part of large industrial compounds where, at one point, multiple blast furnaces were typically standing and operating side by side for efficiency reasons, raw materials were delivered by external elevating mechanisms, and the entire site was accessible by freight trains which delivered the raw materials and carried off the freshly smelted pig iron in ladles.
In many cases, the preserved sites have been deliberately stripped down to minimize maintenance costs; namely, some blast furnaces and related installations have been demolished.

The first such decommissioned blast furnace that wasn't demolished and has been preserved to this very day stands in Starachowice, Poland, and has ceased operation as early as 1968.
