Castel Sant'Angelo, originally commissioned by the Roman Emperor Hadrian as a mausoleum for himself and his family, is a towering cylindrical structure located on the right bank of the Tiber River in Rome. Completed in 139 CE, the building served as a tomb before being converted into a fortress and castle by the popes in the 14th century.
Throughout its history, the site has functioned as a prison, a papal residence, and a strategic military stronghold. Today, it operates as the Museo Nazionale di Castel Sant'Angelo, housing a vast collection of art, weaponry, and historical artifacts that reflect its multifaceted role in Roman history.
