None of the directories listed in Introduction to the Standard Directory Layout page is an obvious candidate.
http://www.sonatype.com/books/mvnref-book/reference/site-generation-sect-dir-struct.html recommends the following structure
sample-project
+- src/
[..]
+- resources/
| +- images/
| | +- banner-left.png
| | +- banner-right.png

| +- architecture.html
| +- jira-roadmap-export-2007-03-26.html
