Discover Rome's hidden layers of history beneath its streets. Travel by an air-conditioned coach and use skip-the-line access directly into three fascinating archaeological finds. Visit the hallowed catacombs where, beneath their persecutors’ feet, early Christians practiced their forbidden faith. Almost 2,000 years ago, this network of secret tunnels doubled as a place of worship and burial ground. As you explore tombs made of solid rock, your local expert guide will describe the intriguing history of this sacred spot.

Next, travel to Basilica of San Martino ai Monti. Dating back to the 4th century, this church is located near the edge of the Parco del Colle Oppio. Admire the stunning frescoes by artists such as Pietro Testa, Matteo Riccione, and Giannangiolo Canini that adorn the church walls, and see the Chapel of Our Lady of Mt Carmel. Finally, visit the Capuchin Crypt on an audio guide tour. Capuchin monks used the bones of their nearly 4,000 brothers to intricately decorate the floor-to-ceiling designs, lending it the macabre nickname of "the Bone Chapel". Open your eyes to the city’s hidden side – and you’ll never see Rome the same way again.
