Esztergom Basilica.

The Esztergom Basilica is the largest church in Hungary and a symbol of the country’s religious and historical legacy. Constructed between 1822 and 1856, this neoclassical marvel features an impressive dome that stands 100 meters tall, making it one of the tallest in the world. Located atop a hill with stunning views of the Danube River, the basilica serves as the seat of the Catholic Archdiocese of Esztergom-Budapest and has been a crucial site for over a millennium. Inside, visitors encounter ornate interiors, including the beautiful Bakócz Chapel, and an invaluable Cathedral Treasury filled with artifacts linked to Hungary's past. The basilica's rich history is further enhanced by its role during World War II as a refuge and its remarkable musical heritage, having premiered Franz Liszt’s *Missa solennis* at its consecration. This architectural and cultural gem is a must-see for anyone exploring Hungary.
