I looked over all the in-game sources on the Towers page, and while they are mentioned several times I didn't find anything that said a) they "hold up the world" or whatever, nor b) that the Thalmor are actively seeking to destroy them, only the MK / IL stuff does. In-game and in novel they're only described as places of "great power" and/or "axes of creation" of Mundus.
