Modruš is a village in the mountainous part of Croatia, located south of Josipdol. The population is 197 (census 2001).[1]
This now small village is historically noted as the seat of one of the medieval Catholic bishoprics, established in 1185 in Krbava and moved to Modruš in the 1460s. It later became the Roman Catholic Diocese of Senj-Modruš. One of the counties in the Kingdom of Croatia (in personal union with Hungary) was named Modruš-Rijeka County after it, too.
