In this paper, we present the HR4EU--a web portal for e-learning of Croatian. HR4EU is the first portal that offers Croatian language courses which are free-of-charge and developed by language professionals. Moreover, HR4EU also integrates bidirectional interaction with some of the previously developed language resources for Croatian. The HR4EU portal offers three general (beginner, intermediate, advanced) and two specialized (Croatian for business users, Croatian for students) Croatian language courses. Apart from language courses, the portal also offers information about Croatia presented via interactive maps, as well as other information, which can be useful to foreigners living or studying in Croatia. Moreover, HR4EU introduces users to language resources and shows them how they can efficiently be used when learning a new language on their own.
