Looming over the Spanish Steps, this landmark church was commissioned by King Louis XII of France and consecrated in 1585. Apart from the great views from outside, it has some wonderful frescoes by Daniele da Volterra. His Deposizione (Deposition), in the second chapel on the left, is regarded as a masterpiece of mannerist painting.
If you don’t fancy climbing the steep steps, there’s a lift up from Spagna metro station.
