Inside Castel Sant'Angelo: Unravel Mysteries and Masterpieces

What is inside Castel Sant'Angelo?

Inside Castel Sant'Angelo, visitors can explore a fascinating blend of history and art. The structure originally built as Emperor Hadrian’s mausoleum has evolved over centuries, now housing the papal apartments, an impressive armory, and rooms filled with medieval and Renaissance artifacts.

Quick fact

Much of the original structure of Castel Sant'Angelo, built by Emperor Hadrian in 135 AD, was severely damaged over the centuries, particularly during the medieval period. By the late 15th century, it was extensively rebuilt in the Renaissance style under Pope Nicholas II, resulting in the fortress-like appearance visitors see today.
