I have been data mining university's, I have focused on old up to the 1300 (as my personal saga only just reached the year 1200). I have plotted them out on a google map, typed in some info about the place (sometimes things that can be used as hooks as well). The reason for doing this was to get a better grasp of how things was in Europe at the time. Non magical knowledge is hard to come by so knowing where and when you have access to it can be useful.
Some small notes about how to interpret the data:
The places is listed with a NAME this is usually the place where it is located. And it is usually just University of NAME. In a few places there is a second name Name (NAME2) this means that there is a connection between these two. Usually one place got moved at some point. The general information should be in the info box.
The NAME is follows by a year. This are most of the time based on the founding date. But several times the founding date is not the date of when there first was meaningful education being some at the location. So because it is the information/data/education that is of importance I have used as early a date as I reasonably could find and validate. I have added the relevant information in the info box. There are also a few dates that have a "~" in front of them this is to indicate a uncertainty, education taking place around this date. Earlier and/or later. If there is a date in ( ) that means this is a later founding date. If there is a DATE-DATE this means the education took place between these dates. If there is DATE-DATE, DATE then the third date indicates when it opens up again. Information about the dates is in the info box.
There is as often as I could find pictures of the place, there "logo", for lack of a better word, and some pictures of the university. The pictures may or may not be of the original place, I have tried to get as original pictures as I could and opted out of pictures if I could not find any good or to new.
The info box Is where I tried to put some information about when education first took place at the location. If I found anything of note that might be used in a plot or hook it is also put here. If I found anything to indicate what type of education they where doing I also put it in. The type of education is listed at the bottom like this *TYPE OF EDUCATION. What is important to know is I only list the type if I can find this is what they teached at the start. If they added something new after a while I also added this followed by a date. A lot of places I could not find any such data on. And what you can find obviously also could change over time.
I have divided the map into two different filters up to the 12th century and places founded during the 13th century.
Here is a link to the map
I hope that you will find the map useful. =) Also I might keep adding things to it in the future as well.
A small side-note about universitys historically. There is as far as I can tell three distinct types. Unofficial places of learning. Places founded/approved by the crown and places founded/approved by the church. When ever the crown of church is involved there is a huge amount of benefits for the students and teachers. Often they did not have to pay tax and where more often then not pardoned for crimes as well. Also, you where not allowed to teach about the church unless the church approved of it. I have no idea what if any the ramifications would be if you disobeyed. Maybe a good plot hook? Also more often then not these places are ether in a church or have ties to the church, even the places not approved by the church.
Also Latin is universally used all over Europe so it is a safe bet that even if you are abroad you can at least speak to people here (and in the churches of coursers).
