Špilas is a local dialect name given to the 13th-century castle and fortress dominating the Brno skyline. Originally intended as a royal castle, it was later rebuilt into a huge baroque fortress and used as a prison. The castle is now maintained by the Brno City Museum.Naming citation (WGSBN Bull. 2, #10, 7), IAU / Minor Planet Center, via NASA/JPL
