SOURCE: Giovanni Battista Piranesi. Vedute di Roma (Rome, [1747?-1788]), pl. 37 NOTES: This church was built by Constantia, a daughter of Emperor Constantine, as a mausoleum for herself and her sister Helena, probably before 354. It has been a church since the 9th century.
NOTES: Castel Sant'Angelo was originally constructed as a mausoleum for the Emperor Hadrian in 135-139 AD. The bridge, built at the same time to connect the mausoleum to the Campus Martius, was named Ponte Elio (Pons Aelius). When the mausoleum became a castle in 401 AD, it was renamed Castel Sant'Angelo and the bridge took the same name.
NOTES: The Emamzadeh Darb-e-Emam (or Darb-i Imam), which means the shrine of the Imams, is a funerary complex consisting of an ancient cemetery, shrine structures, and courtyards representing different construction periods and styles within the present day Dardasht quarter of Isfahan. The complex dates back to 1453, but has been added to over the centuries, particularly during the Safavid period, when the two domes were added in 1602 and 1671. A second tiled portal was added in the 18th century and a hospital built on part of the site in the 19th century.
