2 Euro coin lockers are available in the entrance hall for safekeeping of coats and bags. To close the lockers, you need a 2 Euro coin as a deposit.
The lockers are for daily use, and must be emptied when you leave the building. If you do not empty your locker, the 2 Euro coin will be forfeited when the lockers are checked and emptied by university personnel (see University Fee Rules for the University Library).
