No one's going to get lost or tired touring the Old Town island of Kostanjevica – but you will possibly be charmed. Walk 400m up Oražnova ulica and 400m down Ulica Talcev and you’ve seen the lot.
On Kambičev trg, across the small bridge from the bus stop (but enter from Oražnova ulica), stands the Church of St Nicholas (Cerkev Sv Miklavža), a tiny late-Gothic structure. The presbytery contains brightly coloured frescoes of scenes from the Old and New Testaments painted in 1931.
About 200m northwest along Oražnova ulica is a 15th-century manor house containing the Lamut Art Salon , a branch of the Božidar Jakac Art Museum.
Continue along Oražnova ulica, passing a somewhat crumbling fin-de-siècle house (No 24), to the Parish Church of St James (Župnijska Cerkev Sv Jakoba), a 13th-century Romanesque building with a mostly baroque interior. Above the carved stone portal on the western side are geometric designs and decorative plants and trees. On the south side is a 15th-century depiction of Jesus rising from the tomb, as well as 1800s grave markers embedded in the wall.
Ulica Talcev, the island’s other street, is lined with attractive ‘folk baroque’ houses.
