The RIMROM project aims to develop a more social and inclusive Europe through the promotion of cross-border collaboration. Uniting two states with different regulations and languages, the project will enhance Roman cultural heritage with training courses, Italian-Slovenian events, and multilingual workshops. The goal is to provide an integrative experience for visitors to GO!2025, enhance the skills of Roman heritage interpreters, and promote tourism and small business development. The project will help consolidate the role of Roman heritage and sustainable tourism by promoting cross-border cooperation and optimization of sector practices. At the conclusion of the project, the results will be made available to the public, contributing to the enhancement of the cross-border area in the Interreg Italy-Slovenia program and beyond.
