In the park around the palace two canons for launching torpedoes are found , reminding us that this weapon was invented ( by the Croat Ivan Lupis ) , developed , first tested , and then for dozens of years produced in Rijeka .
U parku ispred muzeja nalaze se cijevi za lansiranje torpeda koje nas podsjećaju da je ovo oružje zamišljeno ( Hrvat Ivan Lupis ) , razvijeno , prvi put isprobano a zatim i niz desetljeća proizvođeno u Rijeci .
