FortNet is a website created in WordPress, along with which there is also a corresponding mobile application created using Flutter technologies. It is a tourist application made with the aim of connecting Herzegovinian fortresses from the Middle Ages together with Montenegrin Austro-Hungarian fortresses. In this way, the application combines the presentation of cultural, historical, and natural heritage with attractions, accommodation facilities, and eno-gastronomic content that are connected to the location where the fortress is located. The application also serves to inform and educate tourists who come to the area as well as easier to find other content to visit. The application consists of 4 categories: eno-gastro, active tourism, accommodation, and heritage.
