Introductory Note: The following is another in a series of articles by JWR that links to some of the thousands of archived SurvivalBlog articles, grouped topically.
Today we address hidden storage spaces, hidden rooms, secret compartments, wall caches, door caches, and related topics.
Delving into SurvivalBlog’s deep archives, which now have more that 27,600 articles, columns, and letters that are all freely accessible, you will find many articles on this topic. The following is just a sampling:
I highly recommend a paperback book titled The Construction of Secret Hiding Places  which is a succinct “must read” on this topic.
Also, don’t overlook the dozens of videos on secret rooms and hidden compartments available on YouTube. Not only will these give you some good tips, but they are also fascinating to watch.
Closing Note: You can use our recently improved Search box at the top of the blog’s right hand column to find even more articles. (The ones that I’ve linked to are just a sampling.) The new Search tool is much more useful than the old one. When searching, use quote marks around terms that need to appear together, for example “wall cache”. You can also use “AND” in search phrases to combine multiple search terms, such as “velcro and compartment”. – JWR
