According to Google Translate, "las fallas" mean "failures".
"the failues" would be possible, given the right context, but it is much more likely that the phrase is used in reference to the fiesta in Valencia.
You capitalized it in your title (which definitely makes it the fiesta) but did not in the body of your post (which opens up the possibility of "the failures/faults").
