Powder Magazine, Fort Scott national historic site

The powder magazine is the only structure at Fort Scott lined with brick, for the simple reason that brick is resistant to fire. Brick can withstand temperatures up to 1300 degrees without being compromised. Considering the other measures taken to protect the magazine (thick walls and a lightning rod), it made sense for it to be the only building lined with brick. These measures would have helped keep safe the stores of explosives in the structure.
