The project includes free guided tours which will be organised in 56 towns and cities by members of the tourist guide societies (ZDTVH).
The tours start at noon Sunday at each of those locations covered by the programme.
The association underscores a great attendance of people at those guides last year.
Croatia observes 15 January as a memorial day remembering January 15, 1992 when the member-states of the then European Community (EC) jointly recognised it as an independent state and when Germany, which played a key role in that process together with the Holy See, established diplomatic relations with Croatia.
On January 15, 1992, when Croatia became internationally recognised, the Homeland War was at the height of its intensity and nearly a third of the country was occupied by the Yugoslav People's Army (JNA) and Serb insurgents. Croatia would fully regain control of its entire territory only six years later, after the completion of peaceful reintegration of Eastern Slavonia and the Danube region, that is on 15 January 1998.
