Famous as "the smallest town in the world", situated on the slope above the river Mirna, it preserved all shapes of the medieval urban architecture and organization. It is closed by the complex of the town walls with towers and town gates from 1562. Inside the walls there are intertwined streets paneled with stone, main square and stone benches. Near the town gates there is the Romanesque-Gothic belltower. The parish church of SS. Peter and Paul was built in 1802 on the place of the older church. On the square you can see the town loggia from the 16th or the beginning of the 17th century. It gained the present shape in the 19th century. At the cemetery outside the town, there is the chapel of St. Jeronim from the 12th century, the oldest completely preserved architectural monument of Hum, with valuable paintings. The Gothic chapel of St. Toma from the 15th century lies on the broad highlands north of Hum. Along the local road that goes from Roc to Hum, there are eleven monuments that from the Glagolitic Road (as the from of tribute to the Croatian Glagolitic scholars for raising of the national sprit).
