@Bigdonnyv, I’ve been creating palaces of late in different styles. There are two values that are important to follow that I’ve picked up from reading psychology and reading other people’s tips. They are 1) make it relevant and 2) get to know it well. One value done well can make up for another value done poorly but both together are better. The best tips for getting to know it well are to practice it on everything and write it out.
I started memory palaces as imaginary places. Each location was a number peg selected for the theme of the palace and the number pegs created a story that I could traverse. I did the Gospel of Luke as a hospital since he was a doctor, and the Gospel of Matthew as a math building since he was a tax collector, etc. I called these bottom-up designs since to be relevant I wanted the information to supply the images that worked the best.
Imaginary palaces work the best for long-term information for me. That’s because they aren’t as concrete as real palaces and seem to fade away easily without much review. Real palaces have rich detail and seem to create a stronger impression for a lasting palace that doesn’t mind the information rotating in and out of it. That’s where the tip of using something from your childhood or recent past comes in. But depending on how you are going to use it will determine what kind of palace design would work the best.
Sometimes you make a composite palace. I have a 40 room/background palace under construction with five locations in each. Each room could be a real place from my past but some are just for fun. Part of the reason that the imaginary rooms have to be there is because I like to shore up my traversal with number pegs. So, the first two rooms start with an S or soft C consonant, the next two a T or D consonant and so on.
I’ve put the US states in there and practice while watching Antiques Roadshow programs putting the objects in there under time pressure. I have a story for the Old and New Testament books but might add all of the 66 books in there as well. If I lose my place in the palace, I can start at 10, 20, 30 or whatever. Using the number pegs are stronger than the story that links the rooms together but eventually, it will become easy.
Hope these tips help!
