| 12512 Split | Discovered 1998 Apr. 21 by K. Korlevic and M. Dusić at the Visnjan Observatory. |
| Split is the largest Dalmatian city and the second-largest urban center in Croatia. Located on the shores of the eastern Adriatic Sea, it is a vital link to the numerous surrounding islands. The historic city of Split is built around the "Palace of Diocletian", the world's best preserved Roman palace. |
