Using the remains of an ancient church that sits below the modern structure, it's believed that this rococo church has a history that dates to the fifth century. Home of the Wilten Boys' Choir, the church is known for the figure depicting "Our Lady Under the Four Columns." Inside, you'll find rocaille stucco, ceiling frescoes and gold accents.

According to recent visitors, the basilica is a bit of a walk from Old Town but they say its interiors are gorgeous. Others recommend walking through the small cemetery located outside the church.

The church is open daily from 7:30 a.m. to 6 p.m., except during services when it's only open to worshippers. It is free to enter, though donations are welcome. Visit the basilica's website (in German) for more information.
