Trick rooms and Traps are a feature of 3lbb gaming, and there is no shortage of lists and suggestions available for such things. I can remember, for example, purchasing Grimtooth's Traps as one of my first rpg mail orders, back in the day.
Recently however I began to want a more "period" list for the dungeon I've been working on. What we find in the 3lbb's Underworld and Wilderness Adventures are a number of suggestions, mostly on pages 5 and 6. So I took these suggestions and listed them in a numbered table. By themselves the U&WA material is a bit scant, but Supplement I Greyhawk, pages 61-63 adds quite a few more suggestions, and the 1975 Origens I version of the Tomb of Horrors as reported by Swanson in Alarums and Excursions suggested a couple more. I also grabbed on to the otherwise unmentioned tricks and traps in Gygax's dungeon generator found in Strategic Review #1.
My guidlines were that I was looking strictly for architectural features built in to the dungeon. So things like magic statures or gambling halls found in the Greyhawk supplement weren't included, nor was anything that was redundant. Things that were similar tended to get lumped, such as pits of various depths.

Room with a shifting section of wall; a secret die roll
determines which way it will go: 1 = N., 2 = E., 3 = S., 4 = W., and 5 &

shifts to.

process can be repeated with one or more additional rooms in series.

This is very helpful.
I've been working on a list of table for random dungeon generation that start with treasure (in order to build a theme) first, thus inspiring the mapping of a certain design, later.
This is really helpful so I am going to grab it! Thanks!
