Where did the Red Brick Road lead to?
In the movie of "The Wizard of Oz", the beginning of the Yellow Brick Road is entwined with the beginning of a Red Brick Road. The Yellow Brick Road led to the Emerald City. Where did the Red Brick Road go?
Interestingly, I have two (possibly conflicting) answers.
In the 1939 film, a red brick road can be seen starting at the same point as the Yellow Brick Road but going in a different direction. This road does not exist in the books.
No one knows for sure....
In the original series of Oz books written by L. Frank Baum the red brick road goes to the Quadling Country in Oz. Red is the Quadlings' state color.
In his books, the Land of Oz was divided into four quadrants and each was designated a particular color: Winkie Country = Yellow, Gillikin Country = Purple, Munchkin Country = Blue, and Quadling Country = Red. Glinda the Good was the ruler of the Quadlings in L. Frank Baum's Oz series. As her bubble floats away from Munchkinland in the 1939 film, it appears to be following the red brick road. Therefore, the red brick road most likely leads back to her homeland, Quadling Country.
I'm inclined to go with the answer from Askville, since it may simply mean that the road wasn't in the Munchkin town in the books. (I haven't read any of them)
Thanks to Pixel's link, I also did some searching through the books. Not only is he and Wikipedia right in that a "red brick" road is never mentioned, there is a passage that specifically suggests that the road is not red - from The Patchwork Girl of Oz, 84% down the webpage (near the beginning of chapter 25, bolding mine):
Not that the trees and grasses were red, but the fences and houses were painted that color and all the wild-flowers that bloomed by the wayside had red blossoms. This part of the Quadling Country seemed peaceful and prosperous, if rather lonely, and the road was now more distinct and easier to follow.
The map above does appear to be correct, however. The Quadling country is, in general, associated with the color red, and is located in the South. So I feel it's pretty likely that the movie made some slight alterations, such that the yellow brick roads all eventually led to the Winkie country (and from Munchkin country, meant you'd go right through the Emerald City), and the red brick road to the Quadling country. If the movie encompassed more, a purple brick road and a blue brick road may have been added as well.
I just did a full-text search for the string "red brick" in the digital version of The Wonderful Wizard of Oz on Project Gutenberg, and there are no hits. I did quick search through all the other books with Oz in the title and didn't find any hits there either, so this road doesn't seem to be discussed in the books. (See http://www.gutenberg.org/ebooks/search/?query=oz)
@Pixel Interesting, but I'm getting a 403 Forbidden from that link, apparently due to overzealous bot protections. If you look closely at the image, it says in the bottom right, "The International Wizard of Oz Club". Could there be extra canon material, or would that not have been made by Baum?
@Pixel Overzealous indeed, seems to have been based on IP address. I can see it now.
There is one confused aspect in the movie. In the books, there are two good witches: Glinda in the south and another in the north. They were combined in the movie into a single character Glinda, the Good Witch of the North. Also, Iskata, there is additional canon material not written by Baum. The Wikipedia article does an ok job of sorting out which of the many books are/are not canon.
@Izkata, sorry, I edited your post because I didn't realize that there was a comment box. Actually, if you look closely at the picture of Dorthy starting out on the yellow brick road, there appear to be two blue brick roads, coming from where the red brick road is headed, and where the yellow brick road is headed, and ending right where the yellow and red brick roads start, which makes sense seeing as blue is the color of munchkin land, and that is where Dorthy is at that point, although this still doesn't explain why there is no purple brick road, it gives the second theory a bit more support
The Yellow brick road does not just lead to the Emerald City (or beyond it to Winkie County) - it leads in a circuitous path all around Oz, and only eventually into the Emerald City. It would be great if there were roads from each county's capital to each other like that, but if that were the case, there should also be GREEN brick roads leading to the emerald city from each place. The books just don't support this theory though.
