Vrhbosna
Vrhbosna was a medieval district in the Sarajevo field, surrounded by the mountains of central Bosnia. A thirteenth-century royal charter mentions the district and a cathedral of Saint Peter at Brdo. In the fifteenth century the Ottoman commander Isa-beg Ishaković established religious and commercial endowments in the valley; his deed of 1462 records foundations that helped shape the growing town of Sarajevo. The older name Vrhbosna continued to appear in western records.
