One of my favorite monuments in Rome is the Pyramid of Cestius (Piramide Cestia) in Testaccio. It is also the source of my inspiration for my Magical Pyramid Earrings.
Built from about 18 BC–12 BC as a tomb for Gaius Cestius Epulo, a magistrate and member of one of the four great religious corporations at Rome, the Septemviri Epulonum. from wikipedia.
Piramide through the ages.
