The headquarters of the Bank of Italy are in Via Nazionale, in the building constructed by Gaetano Koch in 1892. The majestic dimensions underlined the bank's role as one of the most important political-economic institutions in the newly-born capital and the architect's modern interpretation of a Renaissance style provided a link with Italy's deep historical and cultural roots.

Excavations for the foundations uncovered the ruins of a sanctuary and some patrician houses belonging to Imperial times and built on this side of the Quirinal Hill.
After passing the bank, Via Nazionale descends towards Piazza Magnanapoli, yet another area rich in monuments and memories of the various eras in the city's life.
