Time Out says
Follow the travels of the Seljan brothers
The most unusual section of the Karlovac City Museum that fills the oldest preserved Baroque residential mansion in the historic centre, dating back to the 1600s, displays the exotic remnants relating to the travels of the Seljan brothers, Mirko and Stjepan. Born and educated in Karlovac, these intrepid explorers charted little-known areas of East Africa for the Emperor of Ethiopia before mapping great swathes of the Amazon rainforest. Mirko was last seen paddling up the Huayabamba river and is thought to have been eaten by cannibals. During their adventures, these pioneers collated plentiful artefacts, maps, photographs and drawings, and kept detailed diaries, some of which can be found here.
