Well-preserved old churches, fortresses and castles testify to a grandeur harking back to bygone ages, housing precious works of art of international renown. With its multiple influences, the "Alpine Road of Romanesque Art" embodies an invaluable cultural heritage. In the border area separating the Swiss Engadine and South Tyrol are numerous works of early Romanesque art dating from its most glorious epoch. This includes the Convent of St. John in Müstair, founded by Charlemagne, today a UNESCO World Heritage Site.

In the eastern region of South Tyrol, lies the Venosta Valley, with its numerous Carolingian and Romanesque villages. Together with the Müstair Valley in neighbouring Swiss Engadine, the Venosta Valley is home to some of the oldest existing churches and frescoes in continental Europe. Along the Adige Cycle Route, retracing the ancient Roman road known as the Via Claudia Augusta, lie the Benedictine Abbey of Marienberg (the highest in Europe), the medieval town of Glorenza/Glurns, the St. Veith Church on the mystic Tarces Hill and the pre-Carolingian Church of St. Prokulus in Naturno/Naturns.
