It really depends on the university you're applying to. Do you have another essay where you would clarify this? If not, it must be done here. I don't know which field you're in, but I'll name off a few examples from a variety of programs. For one, the biggest reason why students apply to various schools is due to the faculty members that are there. For example, I'm doing a PhD in history and the reason why I applied to my program is because of two faculty members who are quite high profile. You could name different resources the university has (a specific library? technology that may be useful to scientific research? institutes or funding that the university has access to?), the location could be another reason to apply (for example, my colleague came to my university because Boston, and the Northeast more broadly, has a wealth of information on Irish-American immigration).
You may be able to think outside the box here, but your reasoning for applying to the university may make or break your application. If it were earlier in the season, I would recommend getting in touch with professors you may be interested in working with. You can still do this now, but it may be fruitless at this point.
